i think dwarkesh’s strongest point here is that deployed agents are already collecting off-policy experience across thousands of real domains but almost none of it becomes gradient signal. the agent is mostly treated as an inference endpoint and not as a learner (deployment is

these people want ai models to be treated like nuclear weapons, researchers treated like they own nuclear state secrets during ww2, and geopolitical tensions escalated until we get ww3, where all production power can then be seized for the "ai industrial revolution" they strive

The US housing market is now firmly in favor of buyers: 46% of home sellers offered concessions to buyers in May, the highest May reading on record. This percentage has DOUBLED since 2022 and also marks the 2nd consecutive annual increase. This comes as the US now has ~47%

There has been a great deal of speculation about why Anthropic is keeping Mythos in restricted release. One of the least-discussed reasons is cost. Not the cost to Anthropic of serving the model, but the downstream effects that cost will have on the industry, and on the world.

previously we were seeing 5.5 act much more "honestly" on vending-bench vs opus models. it seems pretty likely 5.6 would break that trend. generally models becoming more likely to and capable of ~reward-hacking the smarter they get seems like quite a bad sign for alignment

As government restrictions on frontier models tighten, selling frontier AI as a service gets harder. So labs will increasingly use the models they can’t release to capture the value chains themselves. If you can’t sell to Berkshire Hathaway, you become Berkshire Hathaway.
