In the limit, the pessimists will eventually be correct. There’s only so many technologies and improvements that can be made under the laws of physics (e.g. Landauer’s limit), and once we hit those real limits, that’ll be as good as it gets.
Of course, the catch that a lot of people might not realize is that a) we’re at least centuries away from hitting said limits, even with aligned superintelligence, and b) those limits are far, far better than what we have and live with today.
