OK, but Altman is complaining about individual users. Nobody said that maxing out my PC for gaming purposes or just to keep Windows from getting sluggish was a waste, pretty much ever.
And, "waste" has an overtone of moral wrong, of "you shouldn't". When before did anyone say that I shouldn't get a nice PC? Never.
So, yeah, moralizing to individual users that they shouldn't buy DRAM so someone else can have it is new.
