Awhile back I talked to a Tools engineer for AAA game studios for a bit (Taylor Hadden).
One thing that I remember very well was how I assumed that a lot of the weight on gamedev was about optimisation and technicals. Not at all. He said that 90% of all game dev time wastes was in making an artistically coherent and good looking game. That was the huge time and money sinker. From Hollow Knight to Assassins Creed.
Also this. For all the "falsehood" of it, raster has been about taking 30 years of progress in making games functional at a lower computational cost per frame.
RT is just brute forcing it. It's great that we don't need to use petty tricks and can just brute force it, it really shows how far we've come, but...it's throwing away a toolchain of 30+ years of experience and techniques for something immensely less cost effective and better.
In a way, it's akin to electric cars: they're pretty much a better technology in every single last way, but they cost a lot more and good old petrol cars happen to work just as fine and to be as refined/optimised as they've ever been.
