In context, this bit is about how to deal with the fact that our intuitions on what's worth it vs not worth it in terms of the time it takes to build are likely out-of-date with these new tools:

> For now I think the best we can do is to second guess ourselves: any time our instinct says "don't build that, it's not worth the time" fire off a prompt anyway, in an asynchronous agent session where the worst that can happen is you check ten minutes later and find that it wasn't worth the tokens.

This shouldn't lead to huge maintenance burden because most of the time you'll throw away the result. It's a learning exercise.
