There are fundamental limits to physics, to space and to time. If the next generation wants cars, single family housing, authentic meat and fish and various other amenities, there needs to be less competition for resources.

As it stands now, technology is not catching up and a smaller percentage of them will have access to those amenities.

We can't just create more oil out of thin air. Progress on batteries is too slow and renewables and electric cars are too expensive. We're already over-fishing and over-farming the earth with our current population. We are missing all of our climate targets, and that's on an earth where most don't live in developed countries yet.

We could replace those needs with technology like VR experiences and processed food for example, but I have a hard time seeing how that will be enough.
