OK, so the other week everyone who was anyone was banging on about the AlphaGo programme from The Google’s DeepMind that can, so far, beat humans at Go. Baruch’s understanding is that this was a different type of AI than we’ve seen with Deep Blue and Watson kicking human butt at chess and Jeopardy. Both of those deployed the main trump card that computers have against human minds — the ability to scan, prioritise, sort and rank huge databases extremely rapidly to come up with statistically likely solutions to well defined questions. All they needed to defeat the humans were mega amounts of computer processing, clever coders, a ludic fallacy and a large, cold room to keep the servers in.
DeepMind, so far as I am told, uses something more akin to analogy in its core processing, with a feedback loop that keeps the focus on a narrowly defined and therefore manageable number of moves. Words Baruch pretends to understand but probably doesn’t, like “neural networks” and “deep learning”have been bandied about. To play Go well, you clearly have to be able to program smart. That said, AlphaGo doesn’t seem terribly parsimonious in its use of processing grunt: a “mere” 2000 CPUs, as well as 280 high end GPUs using what we experts* call parallel processing, so perhaps it’s still just the typical thing of throwing Moore’s Law at something until you have enough computing power to make it work eventually. But it probably isn’t, in which case chapeau, DeepMind.
So overall, it’s mildly interesting, and at a more mercenary level, grist to Baruch’s mill. If the advances made by DeepMind bring us one step closer to the massive disruption digital automation is going to wreak on business and society, then I’m going to be quids in. My current project is about providing investors with an opportunity to take advantage of those transformations, so this can only encourage more people to want to invest when my idea finally goes live. Yay!
We all need to hedge against the coming AI whirlwind, and this is Baruch’s plan. However, his biggest worry is resistance is futile — that even his job as a fund manager is going be replaceable by machines, like all of yours will be. So imagine his horror when he saw this (HT Alphaville) in Wired from back in January.
LAST WEEK, BEN Goertzel and his company, Aidyia, turned on a hedge fund that makes all stock trades using artificial intelligence—no human intervention required.
Oh bollocks, he thought.
But at times like this I think of Douglas Adams, and have learned not to panic.
