To land the plane and give you concrete timelines here, when you talk to folks in the frontier labs, the median, totally reasonable supposition they'll give is that they think it could be anywhere from two to five years to reach human-level AI across the board.
Let's say they're completely off.... That kind of estimate and the amount of change that's implied by that in areas like health care.... It's not just health care, though. In material design, Google DeepMind just came out with a paper where it made essentially 800 years of progress in material science in a couple of months. There's huge potential here.
