GP was stating that YouTube needs to die and you said PeerTube is the alternative that can kill it - unless I misunderstood something.
I think PeerTube is great but it’s always going to be super niche. If it grows to a level that threatens YouTube I am sure that it would also change/exert economic pressure.
PeerTube might kill YT, but definitely not very soon. However before that it can replace YT just for a tiny minority that needs it the most, which is a good step forward.
It's the same as with GNU/Linux. Did it kill Windows? No. But it doesn't matter for me, since I abandoned Windows many years ago.
