It depends on the mechanisms that govern atomic arrangements, doesn’t it? If we have infinite time, and infinite space, and if it was an (essentially) random process, then sure. On a long enough timescale, the probability of that arrangment approaches 1. But I don’t think those are the circumstances that we’re dealing with.
Simple: if what you want is to try to get eyeballs on your art, you’re not going to post it on a website that restricts its visibility. I’m never going to see that much content beyond my own instance. I need to follow the artists individually to see their art, or they need to be somehow connected to someone on my instance.
That’s the ultimate non-starter.
Twitter doesn’t have this problem, and Twitter still works (mostly). It’s still the only reliable source for commissions.
