Why not find a career and job that's enjoyable now without even having to defer all of this for later? Not just in software, but you could be flying planes, be in a travelling circus, learn to be a chef, etc. If the answer is you have too many commitments keeping you tied to your current job, then I'd argue that we should be optimising for that optionality rather than some arbitrary day to end the nightmare 40 years from now

I don't want to fly planes, be in a traveling circus, or be a chef. There are things I want to do, but the money spigots of our society aren't lining up to pay me to do them. I'm all for obtaining optionality through universal income. But optionality means also the optionality to retire (today, not decades from now).

That worked out great for those of us who found software enjoyable...
