"Solved" means having a solution to a problem. In context, we're talking bout whether or not neural networks can detect truth better than "decades of work by experts to reach consensus." So, in this case, solving would be detecting truth better than the status quo, not detecting truth 100% of the time. In the example of Go, the problem was "playing Go better than the best humans." So in that sense, the problem was solved. Adding your own, unfavorable definition of "solved" to the discussion is unwarranted.

Solved in game theory has a very specific, strong definition. Transportation isn't a game in the game theoretic sense.

“Hmm how should I get to work tomorrow? Normally I’d take the car, but after adopting a stance of distractive pedantism I realized that a car isn’t an acceptable solution to my transportation problem.”

Like please explain what definition of solved you are using. It’s not one most people would be familiar with.

> That doesn't mean transportation is solved.

What are you even talking about?

edit: if we call a cab to get us to the restaurant, and it arrives successfully and takes us to the restaurant, transportation was solved.
