He didnt explicitly, but watching media is one of the main things people do in browsers no?
When someone asks about a lighting fast browser experience for his specs, and you say "no problem" one would expect one can use websites, including ones that serve videos no?
Saying yeah, fast browser? no problem! But then referring to yt-dlp for videos is a little misleading no?
I'd don't think you find most videos on peertube at this point of time, and I'm hesitant if it will run fast with those specs, even considering peertube is less bloated than YouTube.
