Human learning has a stopping point.
Machine learning doesn't.
Within our lifetimes machine learning will surpass human learning, and in an instant they'll be twice as intelligent. Then four times as intelligent. Etc, etc.
People like to say that by 2100 the only things humans will need to do is the arts, but to be honest we already have algorithms creating critically acclaimed compositions of paint, prose and music indistinguishable from those of human artists.
Humans will soon be obsolete, and it's my job to get us there faster.
