I really don't see how that is true.

For instance, once you develop atomically precise manufacturing ala Drexler and have a complete model of biology, etc., drive solar panel efficiency to very near the upper theoretical bound for infinitely many junction cells for a raw panel of ~68%, then there isn't really anywhere to go that matters for humans. Material production would be solved, anything you could desire would be manufacturable in minutes to hours, a km^2 of solar panels could power 10-20k people's post-scarcity lives.

You eventually reach the upper bounds on compute efficiency and human upload model efficiency -- unknown but given estimates on upper bound for like rod logic (~1e-34Js/op), reasonably bounds on op speed (100MHz), and low estimates for functional uploading (1e16 flops), you get something in the zone of 0.1nW/upload, or several trillion individuals on 1m^2 of solar panel in space. When you put a simulated Banks Orbital around every star in the Milky Way in a grand sim running on a system of solar panels in space where the entire simulated galaxy has a 15ms ping to any other point in the simulated galaxy, what exactly is this infinite stream of learning? You've pushed technology to the the limits of physical law subject to the constraint of being made of atoms.

Are you envisioning that we'd eventually be doing computation using the entirety of a neutron star or (if they can exist) a quark star? Even then, you eventually hit a wall where physics constrains you from making significant further gains.

There is an ultimate end to the s-curve of technology.

I see your point, however, consider this: to a farmer in 1900, our modern food system is already "end of history" post-scarcity sci-fi. Back then, one farmer fed ~4 people. Today, thanks to automation, GMO and fertilizers, one farmer feeds ~170. We effectively solved the "calorie problem" for the developed world.

But the economy didn't flatline just because we hit THAT manufacturing ceiling. Value simply migrated from manufacturing (growing wheat, assembling cars) to services (Michelin dining, DoorDash, TikTok influencers). Radio did not turn out to be the last useful invention it was predicted to be. Knowledge generation has sped up dramatically.

Your point is fair regarding hardware - eventually you do run out of stars or hit the Landauer limit. But this is exactly Deutsch’s distinction between resources (finite) and knowledge (infinite). Even in a bounded physical system, the "software" (the art, explanations, and social structures) isn't bounded by the clock speed. We don't need infinite atoms to have infinite creativity and knowledge
