They might try to become internet famous, until they realize that it takes a lot more effort to try and get that status, essentially demoralizing them. I am around the Twitch scene a lot and know, from people on there, how many hours they put into their streams to try and create content and support themselves. They're working upwards of 15-16 hours a day, 8-10 of those talking to their chats and being entertaining. Next you'll be saying that why work a job like a lawyer/doctor when they can just memorize lines and perform in a movie?
Not nearly the same. Really. And it doesn't always require hard work to become internet famous. Some times it's mostly luck. Others you play a game showing your boobs and thirsty guys watch you show your non existent gaming skills. Or you just shout in the mic, but are attractive enough for teenage girls to fall in love with you.
I feel the same way about youtubers as I feel about singers and actors. Simple people (especially young people) pay attention to the super successful ones and want to have a career like them. In reality, a tiny percentage of actors/singers make big bucks. Most of them struggle to the point that they need other jobs to support themselves.
So, yes, I think trying to do a youtube chanel instead of studying to earn a degree or something is a very bad idea. There are too many people doing them and it's incredibly hard to stand out. If you're lucky, you may. But how many will be?
I never said it isn't stupid to try and emulate what some of the more famous Youtube/Twitch people do, as that ship is quite volatile and could sink at any time, but I guess that can be said about a lot of jobs (a company could shut down at a moment's notice or get bought out by another company, as an example). It's completely oversaturated and very few people who start up ever get anywhere, even with a lot of hard work on their end. Anyone who doesn't have a backup plan (like having earned a degree) is just foolish, but my initial post is to say that a lot of people do put a lot of hours into getting their stuff together. On the other end of the spectrum, though, there are a few oddities in there that do get lucky and I'm not counting "boobie streamers," as they are just exploiting the system and their horny audience.
