Absolutely, doing easier things at massive scale can still have more value than harder things at small scale.

I actually think exactly what should happen is already happening. All the low hanging fruit from software should be completed over the next decades, then the industry will undergo massive consolidation and there will be a large number of skilled people not needed in the industry anymore and they can move onto the next set of low hanging hard(er) problems for humanity.

Given that almost every major thing in the world runs on some kinds of computers running some software - a lot, probably. The fact that we don't have perfect and infallible robots and universal ways to manipulate the unpredictable, chaotic environment that is the real world (see also - self-driving cars) simply doesn't affect a lot of industries.
