OP is a boring, handwavy steaming hot take without any real substance or critical thought behind it, clearly because the creator is a Youtuber who makes a bunch of CG crap on Youtube. He's a VFX'er coming from the perspective of someone trying to defend slash legitimize their profession and it shows. A lot of this is "no shit, Sherlock" long after this argument's been hashed out on the Internet to hell and back.
There are a lot of problems with CG - it limits actors ability to get into character, when its done poorly it seriously undercuts a film, its commonly used as a shortcut to cut costs, it relies upon a critical abuse of talent and labor, the list goes on and on. People have grown tired of seeing so much bad CG that sticks out like a sore thumb that they're now naturally resistant to it, and looking at the true "great" films of our time the CG is largely unnoticeable and is a background to what's going on on-screen.
Red Letter Media in their prequel reviews breaks it down a lot better, watching George Lucas and his team of people come together to make a trio of space opera epics in the original trilogy be reduced to a single cult of personality sitting with Starbucks in front of a greenscreen studio and watching actors dolled up in robes (that makes no sense within the Star Wars lore, but that's another subject for another time) try to put on a convincing performance to a giant wall of green - it was a shitton of over the top CG that the movie relied on as a crutch when everything else was falling apart, and it shows. The point is you simply cannot use CG VFX as a crutch to stand on.
Mad Max: Fury Road is heavy on CG, yes, but the film is constructed to maintain the viewer's focus and attention on the practical, the tangible, the real - and is paced and constructed in such a manner you don't take the time for your brain to pick out what's real and not real, for the vast majority of the film. That's why it's so effective - the CGI is a background element to enhance the overall picture, not be the picture itself.
TL;DR the OP's video is a depressing sham without substance and RedLetterMedia has done this hot take way better over the years.
