Capitalism also involves risky long term strategies that dont immediately pay off in the short term. I dont think Nvidia made an "error" with RTX, it was a risky move and they were very aware of the potential short term consequences (despite them saying that RTX card sales were "lower than expected"). They may be fast approaching a dead end with normal rasterization and process shrinks which could see their graphics business fail to develop much further in a few years. They need new things to spice up their game and RTX is it. As disappointing it may be in the initial stages, it may eventually inject a second wind in their business to keep them going for longer than would have been possible otherwise. The may "piss off' a few consumers in the process, but this is a very rapid turn-over business where consumers have short attention spans. All it takes is for Nvidia to release newer GPUs with killer price/perf and all past failures are forgiven.
