>I think it might be the way he tries to make it sound exciting for a general audience.
Looking at other videos of Károly Zsolnai-Fehér speaking at a podium to an audience, I think he's genuinely enthusiastic about the subject instead of putting on an act. However, when combining that unusual enthusiasm with a Hungarian accent, some listeners may find it odd sounding.
Probably not, I dislike video / audio as a means to explain and update things, I'll watch the news (because the video adds to the story) but I'd rather have a text version if it's about software things.
That's not ironic to me, the intent seemed to be "papers presented in two minutes", although maybe there's some irony in exceeding that length in every video?
It discusses papers in two minutes, not sure how that's ironic at all, unless you are deliberately expecting that a YouTube channel somehow has written papers rather than videos. These papers would also take one longer than two minutes to read and might not have context from someone in the field, so I'm happy for the expert to go over it for me.
Just because two things sound odd doesn't mean there is anything ironic about it. I could also name my YouTube channel something like Full Orchestral Performances but have them be videos and not music. That's not the definition of irony, but I don't think me explaining it further will make you understand what irony is.
This is a false analogy though. If you had a YouTube channel called Two Minute Full Orchestral Performances I would expect Full Orchestral Performances of two minutes, basically a musical performance.
Since we consume either articles (which are often rated as "This will take you 3 minutes to read") or video, the title is deceiving. Particularly as someone who finds consuming information infuriatingly slow in videos, and prefer to read or scan articles, I find it has a sense of irony to it.
