Indeed. As a quick side-note to this, this is how I address the but tHE EARTh wIlL Be OVerPOpulAteD IF we haD imMORtAlIty! argument. If a human brain needs just 20 watts, and a ‘brain in a jar’ life support system needed 200 watts [to keep that brain alive and functioning forever by endlessly patching it ship of thebes style], that’s the limit case for how little resources you need to support 1 human. [basically a pod in a cluster in space with some sun exposure and robotics for maintenance, with everything closed loop in terms of materials used]
That might not sound like quality of life but recall that a brain in a jar setup can deliver any experience as direct impulses that the brain is capable of perceiving. Simulating a fairly complex VR world might not be all that power expensive given all the ways you can cheat...
