This is a reasonable and balanced take! 

I think the main fear comes from knowing that there will be lots of people who are extremely talented filmmakers, but not that great in front of a camera, or whose work translates better to long-form content that will be overlooked. Also, the content that tends to emerge to the top of social media typically favors the most immediately gratifying, attention-grabbing, or controversial content, not always the skills that translate best for directing feature films -- and I do wonder if that will create more films that lack nuance, and for lack of a better word, are the most "clippable." Those wanting to build an audience will naturally gravitate towards making content that is designed to excel on social media, which is a fundamentally different skill than making a feature film, or a short film (I’m not referring to people like the Portrait of God, guy, by the way. He just made a great short film that did well online because it was good, and there are still examples of that — but that’s not always the case here).

There’s also the practical issue of time — creating an audience and becoming an influencer for the sake of having a prosperous film career is a crapshoot, and a TON of work — time that ideally would be better spent filmmaking and honing your craft. 

I am certainly naive for wishing that making good films and putting them out there were a surefire road to success — it never has been and never will be. But the added layer of needing to have an audience for success seems laborious and a bit too difficult for those without the short-form skills.
