If space lives up to even a fraction of its potential over the next ~10-20 years then robotics is going to grow astronomically as a field. More generally I have not found software to be a longterm satisfying career - the compensation, freedom, and potential are all excellent. You are well compensated, can work from anywhere*, and a single successful side project (don't sign away your rights to code you write outside of work) always has the possibility to blow up into something worth billions - this is really unlike any other "normal" career. But I think there's a reason that there's a growing sect of people leaving to do everything from farming, woodwork, and even welding. Building even simple things in the real world is somehow so much more satisfying.

If I had it to do over again I'd pick a field where software complements something done in the real world - robotics, astronomy, aerospace, etc.
