Playing devil’s advocate here, I say we just push through and go to Mars. Human history is full of biting off challenges bigger than we can chew, but we always find a way to make it happen.

Look what we did in a few short years in the 1960s with rudimentary computers and a limited knowledge of space — we landed on the Moon in the first place.
