I haven't seen this articulation before, and I'm going to remember this one!
In return, I'll share my own reasoning:
Human Life is finite, and there is a real opportunity cost to learning (say) to copy Picasso's style -- you could've been doing something else in that same Time.
However, if you're training a model on the entire career output of dozens of artists, it only needs more electricity + GPUs to do this.
And, transposing this back to the Human realm, there's no way one person can put in that kind of wide effort to learn how to copy dozens of artists' styles in one lifetime.
I really like the way you put it too -- it's a bit more succinct.
