Question Technology; Kip Currier, Ethics in a Tangled Web, December 31, 2018


Kip Currier; Question Technology

Ars Technica’s Timothy B. Lee’s 12/30/18 “The hype around driverless cars came crashing down in 2018” is a highly recommended overview of the annus horribilis the year that’s ending constituted for the self-driving vehicles industry. Lee references the Gartner consulting group’s "hype cycle" for new innovations and technology:

In the self-driving world, there's been a lot of discussion recently about the hype cycle, a model for new technologies that was developed by the Gartner consulting firm. In this model, new technologies reach a "peak of inflated expectations" (think the Internet circa 1999) before falling into a "trough of disillusionment." It's only after these initial overreactions—first too optimistic, then too pessimistic—that public perceptions start to line up with reality. 

We’ve seen the hype cycle replayed over and over again throughout the World Wide Web age (and throughout recorded history), albeit with new players and new innovations. Sometimes the hype delivers. Sometimes it comes with an unexpected price tag and consequences. Social media was hyped by many through branding and slogans. It offers benefits; chief among them, expanded opportunities for communication and connection. But it also has significant weaknesses that can and have been exploited by actors foreign and domestic.

Since 2016, as example, we’ve acutely learned—and are still learning—how social media, such as Facebook, can be used to weaponize information, misinform citizenry, and subvert democracy. From Facebook’s “inflated expectations” Version 1.0 through multiple iterations of hype and rehype, to its 2018 “trough of disillusionment”--which may or may not represent its nadir--much of the public’s perceptions of Facebook appear to finally be aligning with a more realistic picture of the company’s technology, as well as its less than transparent and accountable leadership. Indeed, consider how many times this year, and in the preceding decade and a half, Planet Earth’s social media-using citizens have heard Facebook CEO Mark Zuckerberg essentially say some version of “Trust me. Trust Facebook. We’re going to fix this.” (See CNBC’s 12/19/18 well-documented “Mark Zuckerberg has been talking and apologizing about privacy since 2003 — here’s a reminder of what he’s said) Only for the public, like Charlie Brown, to have the proverbial football once again yanked away with seemingly never-ending revelations of deliberate omissions by Facebook leadership concerning users’ data collection and use.

To better grasp the impacts and lessons we can learn from recognition of the hype cycle, it’s useful to remind ourselves of some other near-recent examples of highly-hyped technologies:

In the past decade, many talked about "the death of the print book"—supplanted by the ebook—and the extinction of independent (i.e. non-Amazon) booksellers. Now, print books are thriving again and independent bookstores are making a gradual comeback in some communities. See the 11/3/18 Observer article "Are E-Books Finally Over? The Publishing Industry Unexpectedly Tilts Back to Print" and Vox’s 12/18/18 piece, “Instagram is helping save the indie bookstore”.

More recently, Mass Open Online Courses (MOOCs) were touted as the game-changer that would have higher education quaking in its ivory tower-climbing boots. See Thomas L. Friedman's 2013 New York Times Opinion piece "Revolution Hits the Universities"; five years later, in 2018, a MOOCs-driven revolution seems less inevitable, or perhaps even less desirable, than postulated when MOOCs had become all the rage in some quarters. Even a few months before Friedman’s article, his New York Times employer had declared 2012 as “The Year of the MOOC”. In pertinent part from that article:


“I like to call this the year of disruption,” says Anant Agarwal, president of edX, “and the year is not over yet.”

MOOCs have been around for a few years as collaborative techie learning events, but this is the year everyone wants in. [Note to the author: you might just want to qualify and/or substantiate that hyperbolic assertion a bit about “everyone”!] Elite universities are partnering with Coursera at a furious pace. It now offers courses from 33 of the biggest names in postsecondary education, including Princeton, Brown, Columbia and Duke. In September, Google unleashed a MOOC-building online tool, and Stanford unveiled Class2Go with two courses.

Nick McKeown is teaching one of them, on computer networking, with Philip Levis (the one with a shock of magenta hair in the introductory video). Dr. McKeown sums up the energy of this grand experiment when he gushes, “We’re both very excited.” 

But read on, to the very next two sentences in the piece:

Casually draped over auditorium seats, the professors also acknowledge that they are not exactly sure how this MOOC stuff works.

“We are just going to see how this goes over the next few weeks,” says Dr. McKeown.

Yes, you read that right: 

“…they are not exactly sure how this MOOC stuff works.” And ““We are just going to see how this goes over the next few weeks,” says Dr. McKeown.”

Now, in 2018, who is even talking about MOOCs? Certainly, MOOCs are neither totally dead nor completely out of the education picture. But the fever pitch exhortations around the 1st Coming of the MOOC have ebbed, as hype machines—and change consultants—have inevitably moved on to “the next bright shiny object”.

Technology has many good points, as well as bad points, and, shall we say, aspects that cause legitimate concern. It’s here to stay. I get that. Appreciating the many positive aspects of technology in our lives does not mean that we can’t and shouldn’t still ask questions about the adoption and use of technology. As a mentor of mine often points out, society frequently pushes people to make binary choices, to select either X or Y, when we may, rather, select X and Y. The phrase Question Authority was popularized in the boundary-changing 1960’s. Its pedigree is murky and may actually trace back to ancient Greek society. That’s a topic for another piece by someone else. But the phrase, modified to Question Technology, can serve as an inspirational springboard for today. 

Happily, 2018 also saw more and more calls for AI ethics, data ethics, ethics courses in computer science and other educational programs, and more permutations of ethics in technology. (And that’s not even getting at all the calls for ethics in government!) Arguably, 2018 was the year that ethics was writ large.

In sum, we need to remind ourselves to be wary of anyone or any entity touting that they know with absolute certainty what a new technology will or will not do today, a year from now, or 10+ years in the fast-moving future, particularly absent the provision of hard evidence to support such claims. Just because someone says it’s so doesn’t make it so. Or, that it should be so.

In this era of digitally-dispersed disinformation, misinformation, and “alternate facts”, we all need to remind ourselves to think critically, question pronouncements and projections, and verify the truthfulness of assertions with evidence-based analysis and bonafide facts.

Are MOOCs Forever?; Chronicle of Higher Education, 7/14/16

[Podcast and Transcript] Jeffrey R. Young, Chronicle of Higher Education; Are MOOCs Forever? :
"Think back to the early days of MOOCs. Professors at Stanford and Harvard and other places were suddenly teaching really big classes, free. Hundreds of thousands of students at once were in those courses. It was an unprecedented giveaway of what had traditionally been the most expensive education in the world.
Back then, I met several students who were binging on the courses the way you might binge-watch a season of your favorite show on Netflix. They took as many courses as they possibly could, powering through and finishing as many as 30 courses in a year. When I asked why they were in such a hurry, the most popular reason was that they thought it was all too good to last. As one of those binging students told me, "I’m just afraid this whole thing might end soon." Surely, universities would change their mind about this, or the start-ups working with colleges might lock things up.
Fast forward to last month, when Coursera did something that stirred up all of those concerns again. On June 30 the company deleted hundreds of its earliest courses, as part of a shift to a new software platform. Reaction, as you might expect, was negative on social media and blogs. One programmer called it cultural vandalism...
Hello, and welcome to The Chronicle of Higher Education’s Re:Learning Podcast. I’m Jeff Young, and I recently had the chance to talk with Daphne Koller, a co-founder of Coursera, about those issues."

Cheater, cheater, MOOC beater; Fortune, 8/26/15

Barb Darrow, Fortune; Cheater, cheater, MOOC beater:
"Researchers at MIT and Harvard this week published a paper finding that students taking online edX coursework were able to game the system by logging on as one person to check out online tests, scout out the right answers, and then log in again as themselves to take the test. Needless to say, that takes a lot of angst (and studying) out of the process.
This is not exactly good news for the burgeoning field of massive open online courses (aka MOOCs) popularized by the Kahn Academy but also increasingly embraced by traditional institutions. MIT and Harvard, with many other universities, for example have backed EdX, a MOOC platform, as a great way to provide low-cost education for lots of people and narrow the skills gap. EdX itself is a technology platform for packaging up and deploying online classes and is backed by MIT, Harvard, University of California at Berkeley, Dartmouth, and other schools. Students typically can use edX to earn certificates but not degrees at the affiliate schools.
According to an MIT News report, the paper’s co-author Isaac Chuang, an MIT professor of electrical engineering and physics, said as they analyzed student data, they noticed that some users answered questions “faster than is humanly possible.”"

Keeping an Eye on Online Test-Takers; New York Times, 3/2/13

Anne Eisenberg, New York Times; Keeping an Eye on Online Test-Takers: "The issue of online cheating concerns many educators, particularly as more students take MOOCs for college credit, and not just for personal enrichment. Already, five classes from Coursera, a major MOOC provider, offer the possibility of credit, and many more are expected...The developing technology for remote proctoring may end up being as good — or even better — than the live proctoring at bricks-and-mortar universities, said Douglas H. Fisher, a computer science and computer engineering professor at Vanderbilt University who was co-chairman of a recent workshop that included MOOC-related topics. “Having a camera watch you, and software keep track of your mouse clicks, that does smack of Big Brother,” he said. “But it doesn’t seem any worse than an instructor at the front constantly looking at you, and it may even be more efficient.”"
