Month: September 2017

Last weekend Michigan Tech was privileged to host Silicon Valley entrepreneur and writer Martin Ford, author of the NY Times bestseller Rise of the Robots, which is all about the disruptive changes in the recent past and future in the areas of robotics, control, and automation, and the implications for our society and our economy. I was able to join Mr. Ford for a couple of different question-and-answer sessions with interested faculty, and to attend his presentation at the Rozsa Center which was open to the general public. I found the entire day to be stimulating and compelling, and I was very happy about the fact that Career Services and the Rozsa Center were able to work together and pull this off. The evening presentation was very well attended and included a lot of students. I was impressed that so many people were willing to give up their Saturday to hear a PowerPoint presentation about automation – but it really was that good.

Ford’s basic premise was twofold. First, although there have always been concerns raised about changes in employment and the economy due to technological advances, going all the way back to the Luddite movement in 1811, this time things are different due to the nature of the technological advances themselves, primarily in the area of artificial intelligence and deep learning. Second, there has been a marked shift in the relationship between worker productivity and worker compensation, that has led to increased inequality and that will probably continue into the foreseeable future.

The argument that “this time it’s different” centers around the sudden relevance of artificial intelligence and machine learning in engineered systems. Artificial intelligence has been around a long time, and for most of that time I have thought of it as the technology of the future – always has been, always will be. Now, in the past 5-10 years or so, it is becoming the technology of the present. This is due to a couple of factors. One is, the raw computing horsepower needed to carry out artificial intelligence calculations is starting to become a reality, due to the inexorable march of Moore’s Law (which says that, essentially, computing power per unit area on integrated circuits doubles every 1.5 to 2 years.) The second is the algorithms themselves, which have been steadily improving in academic research labs for many years, and which are now getting a turbo boost of innovation in industrial research labs like those of Google and Facebook, who recognize the importance to their bottom line. As evidence that we have turned a corner in artificial intelligence, Ford and many others love to point to the IBM Watson 2011 victory in an exhibition match of the TV game show “Jeopardy” over two human champions Ken Jennings and Brad Rutter. More recently, a program called AlphaGo was developed by Google DeepMind in London to play the enormously complex game of Go, and in May of this year it defeated the No. 1 player in the world in a 3-game match in Wuzhen. What is particularly interesting about AlphaGo is that it is not based on a set of rules or heuristics, but rather it simply (perhaps not so simply) trained itself to play the game through a process of trial and error using the techniques of machine learning. This whole field of “deep learning”, based on artificial neural networks made bigger and better as a result of Moore’s Law, is taking Silicon Valley by storm and has really transformed the economic focus there from electronics to software.

[Aside: I have always maintained that the IBM Watson Jeopardy match was not a fair fight. To make it fair, the entire computing platform and its database would have to fit into a box no bigger than 1500 cubic centimeters, consume no more than 20W of power, and be silent when others are speaking. Watson was a very large computer consisting of multiple servers in a separate room with a very loud air conditioning system, and it had access to huge databases of information. Human players are not allowed to “phone a friend” during the match. The counterargument, I suppose, is that the human players had the advantage of 30+ years of training.]

The starting point for Ford’s argument on the economic disruption of automation is in the relationship between worker productivity and worker compensation. In what is considered by the many the “golden age” of American manufacturing, post-WWII, advances in tools and technology allowed workers to become more and more productive, according to a metric of goods and services produced per unit time. As a result, workers became more and more valuable and thus wages went up in lock-step with productivity. Sometime in the mid-1970s, however, this coupling was broken. Worker productivity continued to go up and up, but wages became flat. Ford often made the statement that, adjusted for inflation, American workers have not received a raise in 40 years. He attributes this to a shift from a situation where tools helped human workers be more productive, to a situation in which tools can simply replace the human workers. The situation continues to this day, and the outlook is for it to continue even more rapidly, leading to greater levels of income and wealth inequality and hence social disruption.

Asked whether he was an optimist or a pessimist, Ford responded that he was a pessimist in the short term, based on the realities on the ground, but that he is still an optimist in the long term when he thinks about human resilience and ingenuity. There are some serious problems we are going to have to come to grips with, but if we can work together to recognize and solve those problems, and maybe even get out in front of them, then there is still hope. He is realistic, but not all doom and gloom. I did find his approach different, and more down to earth, from that of other futurist authors I have read lately, some of whom are wildly optimistic about the future of the human race and its relationship to the machines we are creating.

I found myself nodding in agreement with most of the Ford’s points, and had my own takeaway messages. The first is, and I realize this may sound a bit selfish, this is a fantastic time to be an electrical or computer engineer or computer scientist, about to be entering those fields. The technologies of robotics, control, and automation are advancing rapidly, and the advances are not about to stop. We are the ones who are creating this technology, and thus we are the ones who are going to be in demand in the next few decades. Ford himself, knowing that he was at a technological university, made a couple of offhand remarks to the effect that “you guys are going to be OK for a while.” Those who are losing out socially and economically could say that we are part of the problem, and they may very well have a point, although I think as well-educated problem solvers there is every reason to think we can be part of the solution as well. But, setting that aside for a moment, from the individual point of view I would have to say that I cannot imagine a better career to be considering right now than something in the intersection of EE, CpE, and CS.

As evidence of that I would point to our very own Career Fair, which was held this week. Over 340 companies were on campus recruiting Michigan Tech students for co-ops, internships, and full-time. My friends over in Career Services tell me that everybody – everybody – is looking for more electrical engineers and computer engineers. We cannot fill the demand right now of all the companies looking to hire our students. This story is reflected also in national starting salary data. According to the Spring 2017 report of the National Association of Colleges and Employers (NACE) which covers hiring of the Class of 2016, the top starting salaries by major in the nation, for groups with sample sizes of 500 or more, were:

Computer Science $78,199
Computer Engineering $74,439
Electrical Engineering $70,950

In the interest of full disclosure, Petroleum Engineering and Operations Research were higher, with sample sizes of 184 and 64 respectively. Petroleum Engineering used to be much higher, like over $100,000, but that has come way down and is now comparable to Computer Science.

These salary numbers are echoed locally. According to our Career Services 2016 Annual Report, Michigan Tech electrical and computer engineers (which were lumped together) had a 99% placement rate and an average starting salary of $65,951, which was highest among majors in the College of Engineering. ECE was second only to Computer Science, which did very well with an average starting salary of $78,333. The ECE figure is lower than the national average, but it is worth pointing out that many of our graduates take positions in the upper Midwest which has a lower cost of living than California. Our starting salaries are very close to what is reported in the NACE survey for the Great Lakes Region: EE $65,815 and CpE $67,610. Our Career Services numbers are self-reported and must be taken with a grain of salt; nevertheless there is no question in my mind that our graduates are doing very well. I never hear complaints otherwise.

A second point I want to make that was sparked by Martin Ford’s presentation, although tangential to his primary message, has to do with the ascendancy of the overall field of computing relative to engineering. He said it right out of the gate, that all the action in Silicon Valley right now is in artificial intelligence and deep learning. Silicon Valley got its name and its reputation from the design and manufacture of integrated circuits, but that is now taking a back seat to software engineering. The four U.S. corporations with the largest market cap right now are Apple ($791B), Google/Alphabet ($662B), Facebook ($490B) and Amazon ($459B). Apple still manufactures products, and Amazon manages a massive product distribution system, but even so the backbone and the core competency of these companies is essentially software. There are areas where software engineering intersects traditional engineering, to be sure, and the most visible example of that right now is in autonomous vehicles. The reason that Google can get into this game in the first place is that they do not have to design the power train. The value added by taking a traditional vehicle and making it autonomous comes from a suite of sensors, a trunk full of computing hardware, and all the cognitive data processing and artificial intelligence algorithms that end up controlling the accelerator, the brakes, and the steering. I predict that over the next 10-20 years we are going to see a lot more of these systems where the technological advances are primarily on the computational side, not on the physical side. I also believe that we need to be doing more to prepare our engineering students for a world that will be dominated by computing and software, and I will have much more to say about that in future columns.

Clearly my two take-away messages above were not really what Martin Ford came to talk to us about. In the end he advocated for a couple of things. One was more education in the social and economic impact of robotics and automation, which is certainly something I support and which would make all the sense in the world as part of our general education program. The second was starting a conversation around the idea of a guaranteed universal income. I think he is an proponent for this idea, but he recognizes the enormous political challenges and was content on this trip just to get people to start thinking about it. So, I am starting to think about it. I’m not ready to jump up and down arguing on either side, but am willing to learn more and have the conversation.

Fall is coming slowly to the Keweenaw this year. It’s been a wet summer and fall, so the colors should be pretty good as long as we can get a good cold snap to bring them out. Not seeing that in the forecast yet. Have a great weekend everyone!

This weekend Michigan Tech welcomes a special guest to campus. Martin Ford, Silicon Valley entrepreneur and author of the bestseller Rise of the Robots, will be here tomorrow to spend a day with faculty and students, and to give a presentation that is free and open to the general public. That’s Saturday, September 23, at 7:30pm, in the Rozsa Center for the Performing Arts, for those that are nearby and interested. I plan to spend a fair amount of time with Mr. Ford, both socially and as part of his schedule of speaking events, and am looking forward to that. Since I see robotics, control, and automation as a important strategic growth area for the ECE Department, I thought this would be a golden opportunity to share some thoughts on the topic. It also makes sense to put those thoughts together after this weekend’s activities, not before. Until then, Happy Autumnal Equinox and have a great weekend!

Today is the last day of our first week of the fall semester, and students are already getting their first break from classes. Later today is K-Day (short for Keweenaw Day), an outdoor event with food, music, and lots of practical information about activities at Michigan Tech, held at McLain State Park, on the shores of Lake Superior about 10 miles from campus.

The weather for K-Day promises to be absolutely beautiful, which is in contrast to the cool, rainy weather that we have seen recently. We joke a lot about our “reliable crummy weather” but in truth things here are pretty benign, and I even include our winter snowfall in that statement. We have nothing that compares with the devastation caused by Hurricane Harvey in SE Texas, or Hurricane Irma which has wreaked havoc in the Caribbean and is bearing straight down on Florida. I’ll take the rain any day over the drought in the western U.S. which has led to practically apocalyptic wildfires that are barely making the news. My daughter, a college student in Bellingham, Washington, came home to visit this week, and as she got off the plane she remarked that this is the first time she has been able to breathe clean air in days. So, we count our blessings, and of course our hearts go out to all our fellow citizens whose lives are being negatively impacted by these weather events.

This weekend I hit a personal milestone – my 60th birthday is this Sunday, September 10. It is not really an accomplishment of any sort, other than just having lived this long, but I plan to celebrate nonetheless. I have never been shy about birthdays, and am not one of those people that tries to ignore the fact that I am a year older. Party on, that’s what I say!

I understand that a person’s 60th birthday is a major life event in Chinese culture; it has something to do with the 12 years of the Chinese zodiac and the belief that going through that cycle five times represents the completion of an even larger cycle (I defer to my Chinese friends and colleagues for a better explanation.) When my PhD advisor, Prof. Bede Liu of Princeton University, had his 60th birthday, a bunch of his former PhD students organized a big surprise party and people flew in from all over the country to celebrate with him. We even held a mock PhD oral qualifying exam for him, with former student Dave Munson (later Dean of Engineering at the University of Michigan, now president of Rochester Institute of Technology) presiding. That was 23 years ago, and Bede is still going strong. Coming up on this weekend brings back fond memories of Bede and how I still reach out to for him for advice on major life decisions – like a marriage proposal in 1994, and coming to Michigan Tech in 2008.

As is often the case with milestones in life, this is a good time to look forward with optimism and resolve. This academic year I am starting my 10th year at Michigan Tech, and my 4th 3-year term as department chair in the ECE Department. I feel reasonably confident that I still have something to offer, and am eager to do what I can to help move the department and the university in the right direction. This is not to say there is no room for improvement! Most of what I have learned about university administration I have learned on the job, and I am still learning. I have gotten a lot of very good advice over the years from colleagues and mentors, notably the namesake on my professorship Dave House. Dave is fond of saying “Experience is something you get right after you need it” and I have seen that play out many times.

I have also seen the importance of clear, concise communication in my position, and so I greatly appreciate the keynote presentation we had yesterday evening for all the first-year engineering students at Michigan Tech, given by Libby Titus, a Michigan Tech Environmental Engineering alumna and a technical communications expert at Novo Nordisk. Her topic was the importance of communications skills, particular writing skills, for professional engineers. I thought all of her points and her advice were spot-on. One point that she made is that the technical skills acquired in engineering school, as difficult and challenging as they seem to students at the time, are in retrospect easy compared to all the interpersonal skills that are required in the workplace. Communication skills are particularly important, and people who are effective in communication are the ones who will reach a large audience with their brilliant technical ideas. “Engineering and science are group activities” was a phrase she repeated a few times. I especially appreciated the point she made about the importance of using correct grammar in all forms of written communication. Readers of my “Rants from the Grammar Maven” column from earlier this summer can imagine me nodding in violent agreement during that part of the talk.

As much as I agree with what was said at the talk yesterday, I will counter with one point. We have a lifetime to acquire interpersonal, management, and leadership skills as we mature, but the best time to learn math, science, and engineering is when we are young. So to all our engineering students in attendance yesterday, I would say that our speaker was 100% correct in everything she said, but don’t let that stop you from getting your geek on while you are here at Michigan Tech. This is the place to become the technical expert you want to be, or at least to get started in that direction. Yes, you need to be a good communicator, but you have to have something to say, and the best way to do that is become a great engineer first. This is the old “build your house on rock, not on sand” argument that I have used before. Our educational programs in engineering are set up to help you succeed as technical experts, and all the feedback we get from alumni and industry partners tells us that our approach based on strong fundamentals works. In other words, enjoy K-Day, but be ready to hit the books next Monday!

Greetings to everyone from the chair’s office in the ECE Department! Here we are again, at the cusp of a new academic year at Michigan Tech. The new students have already been on campus for a week, for orientation, and classes start next Tuesday. As much as I love the beautiful quiet summers here, I get energized by the new and returning students, the new faculty members across campus, and the overall “buzz” of activity that accompanies the new year. Game on!

One little indicator of the increased level of activity is the increase in my e-mail. I have a nerdy little system where I track my e-mail pretty carefully, in an effort not to lose or overlook stuff, and part of that includes jotting down the number of e-mails in my inbox over every 24-hour period. Over the summer, right up until last Friday, that number was just under 100 e-mails per day. Starting this past Monday, that number jumped up to an average of 143 per day – a 43% increase! Not all of those required immediate action on my part, thank goodness. Our provost, Jackie Huntoon, tells me that she processes around 400 e-mails a day, and I don’t know how she does it. If one can handle 100 messages an hour, which is about my pace, that means spending half the day just conducting business by e-mail. I do notice that on those days where I am sitting in my office sending out e-mails to everyone, I end up with a lot more in my inbox. Funny how that works. Elon Musk, the entrepreneur behind Tesla and SpaceX, joked in an interview recently that e-mail was one of his “core competencies” although based on my experience I’m not entirely sure he was kidding.

Interested readers of FWF, if there are any, may notice that I kind of disappeared in the month of August. I don’t have much in the way of explanation, other than 1) I got busy, or 2) I got lazy. It actually was a busier August than usual. At any rate, I am back in the saddle and ready to share with you more random thoughts on a weekly basis as the semester progresses.

Today I will play “catch-up” with a few paragraphs about what has been on my mind the past month. Any of these topics could have turned into an entire column but I will try to keep it brief.

Alumni Reunions. Michigan Tech held its annual reunion celebration on campus in the first week of August. As always it was great to re-connect with so many Huskies from our past. For the second year in a row the pasty picnic was moved indoors to the MUB due to the threat of rain. Last year it was just that – a threat – but this year it rained cats and dogs so moving it was a good call. [My all-time favorite kid joke: “Hey, it’s raining cats and dogs!” “I know, I just stepped in a poodle.”] At the Friday night awards dinner, we gave the “Honorary Alumni” award to our good friend John Dau from DTE. This award is given to someone who is not an alumnus of Michigan Tech but who has been so engaged with the university that we can pretend he or she is anyway. That was a wonderful evening and I can’t think of a more fitting recipient than John. The entire week is a good opportunity to remind the alumni, and ourselves, that they carry the Michigan Tech “brand” with them their entire lives, and anything we do to move the university forward is a positive reflection on them, even when they have been away from campus for many years.

Copperman Triathlon. I bring this up just as an example of how wonderful it is to be in the Copper Country in the summer (see paragraph 1). The Copperman Triathlon is a very well-run local athletic event up in Copper Harbor, and I have enjoyed participating in it several times. It was held on August 5 this year. The distances are a little bit non-standard, but it is close to Olympic distance – 1/2-mile swim, 23-mile bike, 5-mile run. It can be done individually or in teams – I have done both – and this year I was on a team with Jesse Depue, daughter of retired Michigan Tech colleagues Chris and Carl Anderson, and Joan Becker, our very own Graduate Program Coordinator in the ECE Department. Our team name was “Trust Me, I’m an Engineer”. Jesse absolutely crushed it with a 13-minute swim, and Joan was flying on the bike at 1:12:30. I turned in a mediocre 47 minutes on the run, but hey, I was off the couch and enjoying a stunningly beautiful day in the Keweenaw. I’ll take it.

Charlottesville. From the sublime to the despicable. The events in Charlottesville really set me back and may have had something to do with why I just stopped writing for a couple of weeks, because I had such a hard time finding the words. It goes without saying, but I will say it anyway, that hatred, racism, white supremacy, Nazism, the KKK, and everything that goes with them and everything that they stand for are absolutely deplorable. What is more disconcerting to me is that there is even any debate about this. Seriously, how hard is it to condemn Nazis? There was no end of commentary to be found on social media, and two videos I really liked came from Arnold Schwarzenegger and Jim Jefferies. Schwarzenegger grew up in Austria, and in his video he commented on the soul-crushing effects of Nazism on those who served, and lost, in the German army in WWII. Jefferies, an Australian comedian and fairly recent addition to the Comedy Central line-up on cable TV, made a serious point about how we cannot pretend these neo-Nazis are not part of us (I will skip over his anatomical analogy, even though it was pretty good. Google it.) To his point, we as electrical engineers, computer engineers, and computer scientists have to come to grips with the fact that something we have created – the Internet – has a lot to do with the resurgence of hatred in our society. I have seen some of this stuff, and it is appalling to read what these cowardly little Internet trolls are saying about their fellow human beings under the cover of anonymity. I spend a lot of time here extolling the virtues of all the good things that electrical engineers have brought to this world. The Internet is one of those things, but it has a dark side that is way worse than anyone probably imagined 30 years ago. That hatred is now coming out into the open in ways that we are going to have to deal with, one way or another. I don’t have any good answers – I am just really worried.

Computing at Michigan Tech. Ah…coming back to the collective efforts of those who are actually trying to be a positive contribution to the planet. As we look forward to a season of leadership change here at Michigan Tech, with ongoing searches for the president and three deans, there are some who see a good opportunity for other types of changes as well. I am thinking particularly of change as it relates to computing and information sciences and how Michigan Tech will position itself in the years and decades to come. I count myself among those who would welcome a serious look at this issue. On Friday, August 18, Provost Jackie Huntoon convened a large group of stakeholders in computing at Michigan Tech for an all-day retreat where we explored a lot of different aspects of our approach to computing here. In attendance, and making two powerful presentations, was ECE alumnus Dave House, whom I have written about here before. Dave made the point that technology is changing rapidly in the Fourth Industrial Revolution, and that Michigan Tech needs to adapt and be a leader in 4th IR technologies if we are to remain relevant. I couldn’t agree more. The whole point of the retreat was to open up hearts and minds to the possibility of change; no proposals were put on the table. This is going to be a long process, with lots of input from constituencies internal and external to Michigan Tech, and I have confidence that Provost Huntoon will guide that process effectively. This is something that is on my mind a lot these days, so you may be reading a lot more about it this year.

Personnel Changes. This year the ECE Department welcomes Dr. Tony Pinar as our new Lecturer and coordinator of the Senior Design program. I have asked Tony to concentrate this year on the quality and consistency of the student experience in Senior Design, and I know he will do exactly that. We also welcome Dr. John Pakkala, who will serve as our new Graduate Academic Advisor for course-option MS student. Both Tony and John hold PhDs from the department – Tony just last year under the direction of Prof. Tim Havens, and John many years ago under the direction of Prof. Jeff Burl. We are also dealing with the rather sudden resignation of Associate Professor Shiyan Hu, who has taken a chaired professor position at a university in Europe. I wrote recently about Shiyan’s exemplary professional service activity, and ironically it was this very activity that made him attractive for recruiting elsewhere. This is a blow for the ECE Department, but we congratulate Shiyan on his success and wish him all the best.

Well, I believe this brings us up to the present. We get one more breather, Labor Day weekend, before classes get underway next week. Make it a good one!
