Kids literally aspire to have people watch them play video games for a living now.
the fact that there are thousands, probably tens of thousands of people who make a living playing video games is, well, something. Those aspiring kids probably have a better chance to do that than the kids in Little League do at playing pro sports for a living and certainly more likely to still be doing it in their 30s vs the athletes. Chances and outcomes are likely worse still for actors, comedians, "artists" and musicians.
In my opinion, kids that aspire to such careers should be encouraged, but they should also be realistic about their chances and how much work they may have to put in that will likely add up to nothing. And if they don't plan on busting their ass for years (especially if they want to be an athlete or pro gamer) then they shouldn't even be encouraged.
Of my 4 kids, one had such dreams. Guess which one is still living at home! He does make money off the internet (begging, selling art, Twitch donations), but it ain't close to a living.
