Its all based on winning the competition of engagement of your fanbase, and of the algorithm. In this place 99.9% of videos are not a part of a greater narrative, so your short form consistent narrative towards a crazy idea builds a cult-like following wanting to see if things will manifest (and the algorithm notices).

As you prove yourself in continuing to try, and people become closer to you from consistently seeing you try, theres lots of compounding effects.
