I haven’t been to YouTube in over a decade. Granted, many embedded videos have been hosted on YouTube. I see a need for video hosting, and I’m not sure how that could be sustainable without advertising.

Perhaps there could be something like a a torrent, where people volunteer a certain amount of free space, and files are downloaded in chunks from whomever is available at the time? There could be one central repository, with clones, that keeps track, and distributes these chunks in the most efficient way, and moves frequently accessed data to faster hosts.

I only watch movie and game trailers on YouTube, so yes, it would not bother me if they would be bankrupt tomorrow.

No, not really

Yes hypothetically but only if the youtubers I actually care about have content elsewhere as well. Which is some but not many

Maybe yes, Maybe not.

Most of the youtubers I used to watch years ago have become full-time Twitch streamers and their channels now only serve for highlights. My currently watched content revolves mostly around memes of specific games (most of which may also be available in other platforms at the expense of subtitles).

At least for now I can say that I could live without Youtube as ~90% of my entertainment on the web currently comes from outside the platform.

Not really. Most of the content I watch is from there, from tech stuff to history and current news

While I have revanced on my phone and smarttube on my chromecast, the last time I watched a youtube video for an extended amount of time was two month ago. I did open those apps a few weeks ago, but only to see if youtube finally blocks them. So yeah, I guess I can quit youtube cold turkey now.
