To quote Einstein directly:
-----
Viereck (Interviewer): How do you account for your discoveries? Through intuition or inspiration?
Einstein: Discussing intuition and his confidence in relativity, noting he was convinced the 1919 eclipse would confirm his hypothesis.
Viereck: Then you trust more to your imagination than to your knowledge?
Einstein: I am enough of the artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

I think we need more breakthroughs to build AI that can "draw freely upon imagination" to quote Einstein describing his process.
That is just my guess.
