I feel like a wealthier and wealthier population, slowly shrinking, might be the sustainable future we need. Yes there will be challenges, but geometric, or even linear, population growth of the human species is not sustainable.

I am not necessarily disagreeing but you're description matches closely to one of the distopian worlds in Asimov's Foundation Series.

'Solaria' is this planet of abundance with strict population controls and where robots do all the hard work and wealthy generation for their owners.
