Good luck competing with youtube. They are something called natural monopoly. Even if you get the technicals right, networks effects will kick in. You would need to bring in something revoliutonary to get people to move. Or youtube to fuck up something really badly.

And getting the technicals right won't be easy. Video delivery is not text. Will need dedicated datacenters if you ever get popular and want to keep prices under control. It's expensive.

TikTok and Instagram seem to be doing just fine..

Grayjay can neutralize the network effect
