Then you shit out the slop content and hope your channel picks up. If it fails to drive numbers you abandon it and start with the next channel with the next topic variation. If you get lucky and the algorithm blesses you, you continue to shit out hundreds of videos.

I’m not even sure that you would have to do the abandoning part. There’s likely toolkits that let you upload to multiple channels at once. You can just start them up and spread them out as you wish.
