Russell’s Human Compatible

My school turned back on its mail system as we start a new semester, and a few days ago out popped Stuart Russell’s book Human Compatible (published last Oct.), with a note inside dated March 31. Here’s my review, a bit late as a result.

Let me focus first on what I see as its core thesis, and then discuss less central claims.

Russell seems to say that we still have a lot of time, and that he’s only asking for a few people to look into the problem:

The arrival of super intelligence AI is inherently unpredictable. … My timeline of, say eighty years is considerably more conservative than that of the typical AI researcher. … If just one conceptual breakthrough were needed, …superintelligent AI in some form could arrive quite suddenly. The chances are that we would be unprepared: if we built superintelligent machines with any degree of autonomy, we would soon find ourselves unable to control them. I’m, however, fairly confident that wee have some breathing space because there are several major breakthroughs needed between here and superintelligence, not just one. (pp.77-78)

Scott Alexander … summed it up brilliantly: … The skeptic’s position seems to be that, although we should probably get a couple of bright people to start working on preliminary aspects of the problem, we shouldn’t panic or start trying to ban AI research. The “believers,” meanwhile [take exactly the same position.] (pp.169-170)

Yet his ask is actually much larger: unless we all want to die, AI and related disciplines must soon adopt a huge and expensive change to their standard approach: we must stop optimizing using simple fixed objectives, like the way a GPS tries to minimize travel time, or a trading program tries to maximize profits. Instead we must make systems that attempt to look at all the data on what all humans have ever done to infer a complex continually-updated integrated representation of all human preferences (and meta-preferences) over everything, and use that complex representation to make all automated decisions. Modularity be damned: Continue reading "Russell’s Human Compatible" »
