Again, I doubt there is any chance of this. I really doubt that professional DMing (such as it is) will ever become more than a tiny corner of the hobby. The overwhelming majority of us will play the way we've always played, for good or for ill.
Even things like the "Mercer effect" is just such a small, minuscule drop in the bucket. There are many, many, many more gamers out there who have never seen an episode of Critical Role than have. Most gamers only know the show by name (or maybe by animation).
The existence of professional pretty much anything has largely zero impact on the hobby of whatever activity people choose to do in their free time.
