You're giving humans too much credit. Check out the quiverfull cult. Those people alone could grow to 50 billion within 500 years with that tech.

And you'll also be living on a planet with 50 billion humans. In a sardine can.

Ah, you think when jobs are gone, our wonderful leaders and capitalists will make money rain down from the sky for all of us little plebs that will be unable to work.

Because, you know, the rulers and kings throughout history have been so magnanimous to the commoners.

The entirety of human history.

You do realize we're at a point where technology will eliminate 99% of jobs within our lifetime, right?

You honestly think those in power will be happy with most of the population sitting on their ass doing nothing and sucking up welfare dollars?

This isn't the beginning of the industrial revolution where new inventions created more jobs than were lost...we're well beyond that curve.

Easy to say...until it's your job on the cutting block, and you don't meet the requirements for a new gig.
