I agree entirely with what you're saying, right up until your final question:

> why bother grinding through all the material of climbing Mt. Everest and then attempting it if the helicopter ride is how things are done now?

I think you answered this yourself earlier:

> I think progress is really measured by what humans are able to do and understand

People want to make this progress. Therefore people will "grind Everest" as a mathematical community, and that is maybe not so hugely different from a lot of previous mathematical work.

There's still ample room for creativity: simplifying, generalizing, asking new questions humans are interested in, ...

That grind is emotional. And it's something AI will never have. The desire to solve a problem.
