I dunno - I haven't written off CPU rendering. Maybe if I did animation I would care more. I like the speed of Redshift, but Coronas VFB gets me there fast enough for look dev and for stills, final render times are still great with a threadripper. I'm glad I didn't have to navigate the GPU landscape and market for the last few years - brutal and expensive. I worked for so many years with physical renderer and 3-4 hour renders for one still, that it all still seems amazing and magic to me.
