Because it’s more efficient to work alone

One person can do extraordinary things - ask Beethoven, Picasso, Einstein.

Two people can feed off of each other - ask Watson & Crick, Laurel & Hardy, Lennon & McCartney - but such twosomes are rare, and rarely last.

Three people arrives at the three-body problem, creating unstable dynamics and invariably ending in one of the three being promoted, or one of the three being demoted, or all three flying apart.

The more people you add, the more meetings and messages proliferate, the more politics creeps in, and the lower each individual’s productivity sinks.
