>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?
