I'm sure it will survive.
Many "losers" aka middle class and below mostly spend their time on social medias because they don't have enough money for entertainment and lazy, scrolling and watching videos on cell phones are cheap and effortless.
But, even though this niche can survive, only few content creators can survive from the beginning to present because content creators mostly depends on hype/trend/algorithm.
Algorithm made the battle for attention much harder for creators and they spend thousands of dollars making video thumbnails to attract views and engagement. Fortunately, for the geniuses, creators are comon as mud, they manipulate the population to mainly teach every other creator who are dummies at what they're at. Whoever, invest time and money to understand the algorithm and the right terms that gets people talking wouldn't fear a saturated market, rather milk from it. AI even made the process easier, therefore more hands and money on deck. Creators like Mr beast and Neil Patel have mastered how it all works and are killing it in that field.
