I see your point. But the fact that a very cleverly designed and highly optimized game running on weak cpus can still result in a unique and surprising product that does things most games on much stronger cpus don't even attempt, is proof that by and large cpus are not being pushed by most developers. And that the possibility space for interactive entertainment is large enough to accommodate multiple approaches.
In other words, it may not be possible to make a game like Starfield on the next Switch, but Nintendo have shown that there are other ways to use the cpu to make a groundbreaking simulation game with mass appeal.
