"Oh! A bullshit artist!"
Jul. 17th, 2019 08:56 amYesterday, I had an interview at a company that specializes in niche logistics. Niche logistics is a fancy way of saying "There are special handling needs for the material." This could be something as fundamental as food: it spoils, so you have time limitations, or as complicated as nuclear materials, or simply something so big it needs special permitting to travel, but you still need to get it there "just in time."
My first interviewer was late, so I sat down in a sort of "casual sitting nook for the devs" that, you know, the developers never actually sit in. There was a bookshelf. I was assiduously avoiding looking at my phone so as not to be completely rude. The books were all on the fundamentals of artificial intelligence and data science, and one of them was the classic Applied Linear Algebra. I picked it up and started to thumb through it, remembered something. I put down the book and pulled out my Nook, pulled up chapter one of Francis Spufford's Red Plenty and read it. Spufford's book starts with the discoverer of Linear Algebra having his great insight, and the entirety of the book is a refutation both of his belief in what Linear Algebra was capable of achieving, and of the Soviet Union's belief that it was applicable to human beings. Learning his name, I quickly read his Wikipedia page.
The HR guy came around. "Still waiting?" he asked. I said that I was, my first interviewer hadn't shown up yet. He made a comment about how I'd found something to read. I gestured toward the bookshelf and said, "It's really interesting that these are all old books. There's nothing new about AI and data science. It's just that we have enough CPUs and memory to do it all with."
One of the data science engineers, sitting in the open-bay workspace, looked over and said, "I like this guy already." Which set the tone for the day. Soon thereafter, the guy who was supposed to conduct my first interview showed up.
Later, lunch was in-house at the company, and I sat with a couple of engineers, including the data science guy. Having gotten the gist of what they do, I asked him how the company avoids the Kantorovich pardox: AI systems can only tell you what to do with the resources you have, not the resources you want. The USSR's bid to cybernize its economic base failed for a lot of reasons, but one big reason, aside from the fact that there were no computers fast enough to actually run Kantorovich's math as written, was that even if they could run it, it couldn't adapt to new resources and new human desires based on the availability of new resources, or new human innovations that created whole new levels of resource. (No one knew human beings wanted an unending stream of music entertainment until radio was invented, after all.)
We have a lively conversation about how "the algorithm" (Kantorovich's basic theory and all its consequential descendents) is what we actually run, but "The Algorithm," with the capital letters that most C-Suites put behind it when going onto CNBC or Bloomberg, is more of a business process, with salespeople, inventories from on-the-ground resources like trucks and warehouses, and the ever-changing market landscape of human desires, requiring a team of developers to constantly update both the data sets and the strings of constraints used to analyze it into a short-term outcome.
All that by gluing a few vague things I knew together, and yet it worked okay. It's wasn't entirely bullshit, and I freely admitted that the actual underlying math wasn't something I knew about compared to the economic analysis that Spufford provided and that I could dredge up from my own college major.
(Title explained here, because Dreamwidth isn't very helpful about Youtube videos. Especially trenchant because I, like Comicus, am still looking for work.)
