Moore's law didn't stop, just Dennard scaling. Expect graphics and AI to continue to improve radically in performance/price, while more ordinary workloads see only modest improvements.
Not sure about most of the people in here, but I would get really nervous at the thought of running something that eats up 3x300 watts per hour, for 24/7, just as part of a personal/hobby project. The incoming power bills would be too high, you have to be in the wage-percentile for which dropping 60k on a machine just to carry out some hobby project is ok, i.e. you’d have to be “high-ish” middle-class at least.
The recent increases in consumer power prices are a heavy blow for most of the middle-class around Europe (not sure about how things are in the States), so a project like this one is just a no-go for most of middle-class European programmers/computer people.
Things are getting more expensive here but nothing like the situation in Europe (essentially none of our energy was imported from Russia, historically ~10% of oil imports but that was mostly to refine and re-export, we have all the natural gas locally that we need) The US crossed the line into being a net hyrdocarbon energy exporter a while ago (unsure what the case is recently but it is at worst about at parity)
If by "A bit" you mean about 30-40k
> If by "A bit" you mean about 30-40k
30k more expensive: Than your very-low-end-"average" car.
40k more expensive: Than your average used car.
AFAICS. All in what one sees as an "average" car, I suppose.
