You just get all the shitty parts of living your life with 1000 fake friends(I mean fans) like a hero complex, or an influence complex, or hyper sensitivity to judgement, or addiction to others opinions, or addiction, or suicide, or an inability to communicate with people different than you, or an inability to determine fact from scam, or a permanent state of social one-up-manship, or a constant stream of unending judgement for all your actions in a public forum, or shit tons of fake friends, or complete social isolation in a room of people, or an advocate complex.
All for the pretend reason of "communication" or "connecting the world".
Humans are not built to have close social bonds with 50+ people, it breaks down something about what grounds us. It is why there is a cliché for the famous person with all the bad parts above.
