I think it needs to be made very, very easy (for people who understand Zero about the tech behind it) to set up and host their own peertube “channel” off their home computer. It needs to be just as easy and straightforward as setting up a youtube channel.

Anything that requires people to understand even a bare minimum of tech jargon, or even that exposes them to too much such jargon too quickly, will be too much of a barrier to entry for most people, vs youtube or similar corporate platforms.
