Why not? We build cranes to hoist weights construction workers can't lift. We build electron microscopes to measure things physicists can't see.

Why is it so hard to imagine we can build tools to think thoughts we can't comprehend?

If there's commercial value, I think it's inevitable. We don't fund mathematicians because it's cute when they understand a problem, but because their work tends to have applications with commercial value. The value can be captured without understanding the details.
