>why is all I hear these industry leaders talking about is the threat of extinction? . . . I would love to see a leading lab release research on the health effects of subaudible sound in datacenters

It is straightforward for industry leaders to avoid living near data centers, but there's no way for them to insulate themselves from the extinction threat -- no way short of somehow eliminating the danger for everybody, which seems quite hard to do. Since industry leaders are as self-centered as everyone else, the extinction threat is what they think about.

Also, you describe the extinction threat as "further out". A lot of us think there is already some small amount of AI extinction risk being incurred every day. I.e., we think the period of danger has already begun.

I see. I wonder how this works out in terms of risk/reward. I suppose if you take extinction as -infinite cost than it would be the only issue worth thinking about. Where I think this line of thinking gets challenging is when you need to take in terms of a counter factual. A lot of these were already risks prior to AI (bioweapons, nukes, etc) so what’s the marginal increase in probability as a result of AI I guess is the question which matters. I could get more around this way of framing it than saying that AI itself is the problem. It’s just the being more capable as a species increases risks. I think a lot of these pushback comes from the fact that it’s often the CEO who stands to gain huge by saying his tool is going to end the world so we need public buyin to supporting it. If instead it was just framed as “general technological advancement” is dangerous but potentially worthwhile I think more would be on board.
