I agree that it has some resemblance, but the striking thing about NP-complete problems is that an efficient solution to any of them is an efficient solution to all of them, which makes it worth trying exceptionally hard to find one.

It could be that whatever lackluster expertise you can squeeze out of an LLM is good enough to discourage investment in the real thing since unlike NP-complete problems, expertise isn't generalizable.

Agreed. But there is a new dynamic coming to place. Who can execute faster now that we have AIs? I think the combination of (Good SWE using AIs) collaborating with (Domain Expert using AIs) is the winning team. Things are accelerating on all fronts, the frontier may be jagged but AIs is making progress on all capabilites.
