I linked to modeled organisms, I always feel the HN crowd expects academic level of precision and discussions, but that kills regular discussions I would have at dinner tables with friends, I wish it would be a more casual place. Yes, I meant "behavior of simple organisms" :) Since everything here is loosely defined I feel it's totally pointless to discuss AI, but it's still an intriguing topic. If you look at those…
We can model some aspects of insect behavior. The simulation even looks convincing at first glance (just as simple "AI" looks convincing with a superficial examination of a conversation or text-generation). But we have not been able to fully model the behavior of, say, a bee (which may be enough to solve self-driving cars and then some).

Well, their entire neural system exists to make deviations from Brownian motion. That's the whole point of being an animal not a plant. And doing it well is very very subtle.
First steps towards modelling such behavior can be super-interesting science, not a terrible use of time at all. They can capture a lot of truth about how it works. But like self-driving cars, the thing that kills you is usually a weird edge case, not the basic thing.
