The crybaby dinosaurs who complain about CGI in movies need a few teeth knocked out. Filmmaking is like anything else. You use the proper tool for the job. Sometimes, that's CGI.
I've found that a lot of times people aren't even aware of how much CGI is used in things. They'll talk about a movie or TV show "not using much CGI" and then they find out later that nearly every scene had CGI enhancing the background in lieu of a prohibitively expensive set.
Filmmakers have been using fancy techniques to get around what can be done practically since before CGI or computers were even a thing. Traveling mattes, etc. were just shoddy proto-CGI but made a lot of stuff possible or feasible that simply wasn't otherwise.
