Total, abject failure. Mental illness. Sometimes leading to suicide. Having the most talented of their peer group switch to something they are less likely to waste their whole life on with nothing to show, and the next most talented switch to something else because they are frustrated with the incompetence of the people who remain. Turning into cranks with a 24/7 vanity google alert so that they can instantly show up to spam time cube esque nonsense whenever someone makes the mistake of mentioning them by name. Mail bombs from anarchoprimitivist math PhDs.
