It's not going to give you a mistaken impression of Hambini, he really does have the social skills of a 5 year old and the mentality of a teenager.
He's a bit late on the shimano crank cracking story though, people have been talking about it for years. I agree he usually knows what he's talking about, but I didn't find this particular video to be particularly enlightening. Will be interesting if shimano feels compelled to respond to a 5 year old engineer.
