Why Uber’s business model is doomed

Like other ridesharing companies, it made a big bet on an automated future that has failed to materialise, says Aaron Benanav, a researcher at Humboldt University

Aaron Benanav has an important opinion piece in The Guardian about Why Uber’s business model is doomed. Benanav argues that Uber and Lyft’s business model is to capture market share and then ditch the drivers they have employed for self-driving cars as they become reliable. In other words they are first disrupting the human taxi services so as to capitalize on driverless technology when it comes. Their current business is losing money as they feast on venture capital to get market share and if they can’t make the switch to driverless it is likely they go bankrupt.

This raises the question of whether we will see driverless technology good enough to oust the human drivers? I suspect that we will see it for certain geo-fenced zones where Uber and Lyft can pressure local governments to discipline the streets so as to be safe for driverless. In countries with chaotic and hard to accurately map streets (think medieval Italian towns) it may never work well enough.

All of this raises the deeper ethical issue of how driverless vehicles in particular and AI in general are being imagined and implemented. While there may be nothing unethical about driverless cars per se, there IS something unethical about a company deliberately bypassing government regulations, sucking up capital, driving out the small human taxi businesses, all in order to monopolize a market that they can then profit on by firing the drivers that got them there for driverless cars. Why is this the way AI is being commercialized rather than trying to create better public transit systems or better systems for helping people with disabilities? Who do we hold responsible for the decisions or lack of decisions that sees driverless AI technology implemented in a particularly brutal and illegal fashion. (See Benanav on the illegality of what Uber and Lyft are doing by forcing drivers to be self-employed contractors despite rulings to the contrary.)

It is this deeper set of issues around the imagination, implementation, and commercialization of AI that needs to be addressed. I imagine most developers won’t intentionally create unethical AIs, but many will create cool technologies that are commercialized by someone else in brutal and disruptive ways. Those commercializing and their financial backers (which are often all of us and our pension plans) will also feel no moral responsibility because we are just benefiting from (mostly) legal innovative businesses. Corporate social responsibility is a myth. At most corporate ethics is conceived of as a mix of public relations and legal constraints. Everything else is just fair game and the inevitable disruptions in the marketplace. Those who suffer are losers.

This then raises the issue of the ethics of anticipation. What is missing is imagination, anticipation and planning. If the corporate sector is rewarded for finding ways to use new technologies to game the system, then who is rewarded for planning for the disruption and, at a minimum, lessening the impact on the rest of us? Governments have planning units like city planning units, but in every city I’ve lived in these units are bypassed by real money from developers unless there is that rare thing – a citizen’s revolt. Look at our cities and their spread – despite all sorts of research and a history of spread, there is still very little discipline or planning to constrain the developers. In an age when government is seen as essentially untrustworthy planning departments start from a deficit of trust. Companies, entrepreneurs, innovation and yes, even disruption, are blessed with innocence as if, like children, they just do their thing and can’t be expected to anticipate the consequences or have to pick up after their play. We therefore wait for some disaster to remind everyone of the importance of planning and systems of resilience.

Now … how can teach this form of deeper ethics without sliding into political thought?

Automatic grading and how to game it

Edgenuity involves short answers graded by an algorithm, and students have already cracked it

The Verge has a story on how students are figuring out how to game automatic marking systems like Edgenuity. The story is titled, These students figured out their tests were graded by AI — and the easy way to cheat. The story describes a keyword salad approach where you just enter a list of words that the grader may be looking for. The grader doesn’t know whether what your wrote is legible or nonsense, it just looks for the right words. The students in turn get good as skimming the study materials for the keywords needed (or find lists shared by other students online.)

Perhaps we could build a tool called Edgenorance which you could feed the study materials to and it would generate the keyword list automatically. It could watch the lectures for you, do the speech recognition, then extract the relevant keywords based on the text of the question.

None of this should be surprising. Companies have been promoting algorithms that were probably word based for a while. The algorithm works if it is not understood and thus not gamed. Perhaps we will get AIs that can genuinely understand a short paragraph answer and assess it, but that will be close to an artificial general intelligence and such an AGI will change everything.

What coding really teaches children

You’ve seen movies where programmers pound out torrents of code? That is nothing like reality. Most of the time, coders don’t type at all; they sit and stare morosely at the screen, running their hands through their hair, trying to spot what they’ve done wrong. It can take hours, days, or even weeks. But once the bug is fixed and the program starts working again, the burst of pleasure has a narcotic effect.

Stéfan pointed me to a nice opinion piece about programming education in the Globe titled, Opinion: What coding really teaches children. Clive Thompson that teaching programming in elementary school will not necessarily teach math but it can teach kids about the digital world and teach them the persistence it takes to get complex things working. He also worries, as I do, about asking elementary teachers to learn enough coding to be able to teach it. This could be a recipe for alienating a lot of students who are taught by teachers who haven’t learned.

CSDH / SCHN 2020 was brilliant online

Today was the last day of the CSDH / SCHN 2020 online conference. You can see my conference notes here. The conference had to go online due to Covid-19 and the cancellation of Congress 2020. That said, the online conference web brilliantly. The Programme Committee, chaired by Kim Martin, deserve a lot of credit as do the folks at the U of Alberta Arts Resource Centre who provided technical support. Some of the things they did that

  • The schedule has a single track across 5 days rather than parallel tracks over 3 days. See the schedule.
  • There were only 3 and half hours of sessions a day (from 9:00am to 12:30 Western time) so you could get other things done. (There were also hangout sessions before and after.)
  • Papers (or prepared presentations) had to be put up the week before on Humanities Commons.
  • The live presentations during the conference were thus kept to 3 minutes or so, which allowed sessions to be shorter which allowed them to have a single track.
  • They had a chair and a respondent for each session which meant that there was a lot of discussion instead of long papers and no time for questions. In fact, the discussion seemed better than at on site conferences.
  • They used Eventbrite for registration, Zoom for the registrants-only parts of the conference, and Google Meet for the open parts.
  • They had hangout or informal sessions at the beginning and end of each day where more informal discussion could take place.

The nice thing about the conference was that they took advantage of the medium. As none of us had flown to London, Ontario, they were able to stretch the conference over 5 days, but not use up the entire day.

All told, I think they have shown that an online conference can work surprisingly well if properly planned and supported.

DARIAH Virtual Exchange Event

This morning at 7am I was up participating in a DARIAH VX (Virtual Exchange) on the subject of The Scholarly Primitives of Scholarly Meetings. This virtual seminar was set up when DARIAH’s f2f (face-2-face) meeting was postponed. The VX was to my mind a great example of an intentionally designed virtual event. Jennifer Edmunds and colleagues put together an event meant to be both about and an example of a virtual seminar.

One feature they used was to have us all split into smaller breakout rooms. I was in one on The Academic Footprint: Sustainable methods for knowledge exchange. I presented on Academic Footprint: Moving Ideas Not People which discussed our experience with the Around the World Econferences. I shared some of the advice from the Quick Guide I wrote on Organizing a Conference Online.

  • Recognize the status conferred by travel
  • Be explicit about blocking out the time to concentrate on the econference
  • Develop alternatives to informal networking
  • Gather locally or regionally
  • Don’t mimic F2F conferences (change the pace, timing, and presentation format)
  • Be intentional about objectives of conference – don’t try to do everything
  • Budget for management and technology support

For those interested we have a book coming out from Open Book Publishers with the title Right Research that collects essays on sustainable research. We have put up preprints of two of the essays that deal with econferences:

The organizers had the following concept and questions for our breakout group.

Session Concept: Academic travel is an expense not only to the institutions and grant budgets, but also to the environment. There have been moves towards open-access, virtual conferences and near carbon-neutral events. How can academics work towards creating a more sustainable environment for research activities?

Questions: (1) How can academics work towards creating a more sustainable environment for research activities? (2) What are the barriers or limitations to publishing in open-access journals and how can we overcome these? (3) What environmental waste does your research produce? Hundreds of pages of printed drafts? Jet fuel pollution from frequent travel? Electricity from powering huge servers of data?

The breakout discussion went very well. In fact I would have had more breakout discussion and less introduction, though that was good too.

Another neat feature they had was a short introduction (with a Prezi available) followed by an interview before us all. The interview format gave a liveliness to the proceeding.

Lastly, I was impressed by the supporting materials they had to allow the discussion to continue. This included the DARIAH Virtual Exchange Event – Exhibition Space for the Scholarly Primitives of Scholarly Meetings.

All told, Dr. Edmonds and DARIAH colleagues have put together a great exemplar both about and of a virtual seminar. Stay tuned for when they share more.

The reason Zoom calls drain your energy

Video chat is helping us stay employed and connected. But what makes it so tiring – and how can we reduce ‘Zoom fatigue’?

Many of us have suspected that videoconferencing is stressful. I tend to blame the stress of poor audio as my hearing isn’t what it used to be. His a story from the BBC on The reason Zoom calls drain your energy. There are a number of factors:

  • The newness of this way of interacting
  • The heightened focus needed to deal with missing non-verbal cues.
  • Heightened focus needed to deal with poor audio.
  • Need to moderate larger groups so people don’t try to talk at the same time
  • Audio delays change responsiveness
  • Stress and time around technical problems.
  • Silences don’t work the way they do in f2f. They can indicate malfunction.
  • Being on camera and having to be performative
  • Lack of separation of home and work
  • Lack of transition times between meetings (no time to even get up and meet your next appointment at the door)

I hadn’t thought of the role of silence in regular conversations and how we can’t depend on that rhetorically any longer. No dramatic silences any more.

How to Look and Sound Fabulous on a Webcam – School of Journalism – Ryerson University

Now that all of us are having to teach and meet over videoconferencing on our laptops, it is useful to get advice from the professionals. Chelsea sent me this link to Ryerson professor Gary Gould’s advince on How to Look and Sound Fabulous on a Webcam. The page covers practical things like lighting, positioning of the camera, backgrounds, framing and audio. I realize I need to rethink just having the laptop on my lap.

Econferences: why and how? A blog series

We are all having to learn how to do more remotely. This series of blog posts deals with the why, the what and the how of online conferences.

Open Book Publishers has just published a series of blog entries on Econferences: why and how? A blog series. This series adapts some of the interventions in a forthcoming collection I helped edit on Right Research: Modelling Sustainable Research Practices in the Anthropocene. We and OBP moved quickly when we realized that parts of our book would be useful in this time when all sorts of scholarly associations are having to move to online conferences (econferences.) We took two of the case studies and put preprints up for download:

I have also written a quick document on Organizing a Conference Online: A Quick Guide.

I hope these materials help and thank Chelsea Miya, Oliver Rossier and Open Book Publishers for moving so quickly to make these available.

Codecademy vs. The BBC Micro

The Computer Literacy Project, on the other hand, is what a bunch of producers and civil servants at the BBC thought would be the best way to educate the nation about computing. I admit that it is a bit elitist to suggest we should laud this group of people for teaching the masses what they were incapable of seeking out on their own. But I can’t help but think they got it right. Lots of people first learned about computing using a BBC Micro, and many of these people went on to become successful software developers or game designers.

I’ve just discovered Two-Bit History (0b10), a series of long and thorough blog essays on the history of computing by Sinclair Target. One essay is on Codecademy vs. The BBC Micro. The essay gives the background of the BBC Computer Literacy Project that led the BBC to commission as suitable microcomputer, the BBC Micro. He uses this history to then compare the way the BBC literacy project taught a nation (the UK) computing to the way the Codeacademy does now. The BBC project comes out better as it doesn’t drop immediately into drop into programming without explaining, something the Codecademy does.

I should add that the early 1980s was a period when many constituencies developed their own computer systems, not just the BBC. In Ontario the Ministry of Education launched a process that led to the ICON which was used in Ontario schools in the mid to late 1980s.

In 2020, let’s stop AI ethics-washing and actually do something – MIT Technology Review

But talk is just that—it’s not enough. For all the lip service paid to these issues, many organizations’ AI ethics guidelines remain vague and hard to implement.

Thanks to Oliver I came across this call for an end to ethics-washing by artificial intelligence reporter Karen Hao in the MIT Technology Review, In 2020, let’s stop AI ethics-washing and actually do something The call echoes something I’ve been talking about – that we need to move beyond guidelines, lists of principles, and checklists.  She nicely talks about some of the initiatives to hold AI accountable that are taking place and what should happen. Read on if you want to see what I think we need.
