Is the era of the professional Youtuber Over?

So yes I know this is a bit of an asinine question given that many people still make livings on youtube…… however I feel as more and more viewers join the platform, and views become more and more dispersed…… is it possible this will end? In a roundabout way, might it return to what it was at the beginning: a fun place to post cool stuff, but not a place to expect to draw an income from? Not necessarily saying I think that will be good or bad, just kinda wondering where things are headed
