The real flaw here is that counting arguments is a poor way to make decisions.
“They don’t have the ability to make said meteor strikes” is enough on its own to falsify the hypothesis unless you have evidence to the contrary.
As Einstein said about “100 Authors Against Einstein”, if he was wrong, they would have only needed one.
Art is part of everything, so yes.
Photoshop allows artists to practice and produce works vastly more rapidly, correct errors quite easily, and otherwise do a ton of things they couldn’t do before. Other such programs can do many of the same things.
More artists, plus better tools, plus faster production of art, plus better understanding of the technology of art, probably means that the best piece of art ever made was made in the last few decades.
Indeed, it is possible that more art will be produced in the first few decades of this century than were produced by all of humankind for the first several thousand years of our existence.
