With poor social skills, bad humour and not being able to connect with their audience they won't be successful. Your bias view on streamers only relates to a small percentage. And sure a lot of their audience are younger - they're the ones with the most free time mostly. But that doesn't mean its an easy job to do. Teenagers especially can be tough to entertain at times. I could say football is there to entertain drunks at a stadium but that wouldn't make sense would it. Because my generalisation only refers to a small amount thus making it a useless argument.
