Why hasn't "Twitch but for {food, cars, cosmetics, etc.}" cannibalized youtube yet? Twitch was basically a row boat that cut off Google's battleship by firing a nerf gun across its bow. And they won. And they got acquired for billions. Their product is great, I've learned a fair bit of design and function just by looking at it. I suppose gaming has a large user base that is quick to download and try new tech. It also has a way of slow "dopamine dripping" its audience into spending countless hours of viewership. Does this not exist in other genres?
