I'm on board with those who have said they don't relate much to what is being said. It seemed to be more about the subculture they are part of than their 'type'. (Granted I'm hard of hearing and couldn't make out much of what either INFx contributed- some voices sound too garbled to me, regardless of volume- but based on what I did hear. Also, I only watched half of it.)
I do think it would be interesting to watch a video of these different types with older people though. with a slightly less homogeneous group.
