Mars?

If he’s so smart, ask him if he can fix Chicago’s murder epidemic.

Spain and Italy had lots of problems in 1492. Should Columbus have stayed home and worked on those?

The reason why humans-to-Mars is a stupid idea right now is not because it’s an inherently stupid idea, but because we need better rockets.

"Spain and Italy had lots of problems in 1492. Should Columbus have stayed home and worked on those?"

I never said anything about not trying to go to Mars.

Am just curious why such a "great mind" isn't asked (or, that I have heard, never offers), ideas about "real life" things happening in the here and now.

Maybe it's like asking a painter to do a sculpture. Just not his thing.
