An entitled amateur with a camera who suddenly has no time or respect for others because they make potentially up to 10,000 usd per video. Usually a means to an end, a youtuber lacks intelligence to contribute anything progressive to society and resorts to unorganized and random videos to game a rigged platform algorithm, all for a reason to signify their existence.
My dream is to be a YouTubers so people can like me and I can feel important.
