Yeah, and on a discussion space it’s probably also best that you actually read the comments you’re replying to. He felt that the video wouldn’t teach him anything since he’s considers himself already knowing a lot about the subject.
I just pointed out the irony of you being bothered about him not watching a clickbait video about a topic he believes he already knows more about that such a video can teach. And you then tell him the video makes points he already dismissed.
He might be a bit abrasive how he entered the discussion, but if he works in the industry and knows why awnings are no longer a thing, and already dismisses the points the video made against more modern technologies since he seems to know what modern technologies are actually like… that does seem actually useful to this discussion. I get him not wanting to waste 20 minutes…
