I think most of the actual value created short/medium-term with agents will be in entertainment where things going awry is OK and no action they take can really be catastrophic.
Some people are already spending a ton of time on character.ai (https://beta.character.ai). There are sims-like games like ai-town (https://www.convex.dev/ai-town). My friend and I made an open-source murder mystery novella with agents (https://gron.games).
We found that a lot of the actions they take are pretty low stakes, so the correctness issues are much less important (in ai-town, they just talk with each other, in our game, they just beat you or run away if you interrogate them poorly).
