You and the other commenters are all absolutely right, but that’s not really what I was pointing at.

So far our solutions were more or less understood thru some models of reality that we’ve constructed (on our own), which may or may not reflect reality perfectly, and even if most of us never bothered thinking about these models, some people did and they understood them on a very deep level.

But we may be getting to a point where the problems we need to tackle become too difficult for humans to model, or even to notice their existence, like asking an ant how a Boeing 747 works.

Maybe this was always the case but now it seems like we might have a shot at making these solutions useful even if we have no idea what they’re even solving.
