You’re right, nothing explicitly stated anything about old age, but the study itself has “burials” right up in the headline. IDK if respondents knew those questions were coming when they answered the “lifespan” question, but if they did, I doubt most people automatically assume an increased lifespan meant they’d start being younger than they currently were. That’s all conjecture on my part, but I think it’s similarly plausible as psychological life-weariness as an explanation.
How would computational capacity be infinite in the presence of finite energy?
As I understand it, the theoretical limits on energy efficiency of irreversible computing are a function of ambient temperature (because they involve dumping heat/entropy into the environment). That means if the future universe keeps getting colder as it expands, the amount of computing you can do with a fixed supply of stored energy goes up without bound, as long as you use it slowly enough. That’s basically Dyson’s Eternal Intelligence, though I don’t think anyone knows what the computing architecture would look like. Things like the Omega Point spacetime in a collapsing universe seem more speculative to me but still might be possible.
