Steve Jobs bachelor party consisted of him, a reluctant Avie Tevanian, and one other guy. At that point in his life, he had no true friends. It's not clear how many he ever had, though he had many acolytes and several congenial colleagues.
He was a nasty person, though, like most of us, he improved somewhat with age. He never made it within two sigmas of decent however.
He was also a great gift to me and my family. We got the products of his company, without the displeasure of his companionship. It would, however, have been fascinating to observe his mind. It was extraordinary.
It was also completely unsuited to most of human existence. Even his powers of manipulation could not outweigh the enmity he created throughout most of his life. Were he born at another time, he would have likely died young. Throughout most of human existence his mind would have been a disability, not a gift.
There was a place and time where his mind was perfectly suited, and he had the fortune to be born to that time and to that place.
It's a good lesson on the distinction between adaptive advantage and dysfunctional trait. The distinction is not the trait alone, but its suitability to the environment.
It's also a lesson on the evolution of mind. Human minds are astonishing diverse; in physical terms it's as though a single species could have children with fins and children with wings. A winged mind flies in some times, drowns in others.
