No, it doesn't mean "selfish".
Back when we didn't know autism was a distinct phenomenon from schizophrenia, "autism" was a symptom of schizophrenia. It meant "Disconnected from other people; withdrawn." This is a symptom which also occurs in schizophrenia, where thought disorder, disorganization, and movement and perception difficulties can make it very difficult for the person with schizophrenia to communicate clearly with the outside world, especially with other people.
"Autism" was imported into "childhood autism" once we realized that autism did not involve psychosis and was a separate phenomenon from schizophrenia. The sense that NTs get from autistic people, especially profoundly autistic people or very young autistic children, is that the person is not quite connecting with them--due to the lack of eye contact, odd or absent speech, and difficulty expressing oneself. You also have to remember the very earliest autism theories--they thought it was a neurosis (a mental illness) in which a neglected child deliberately severed contact with the outside world. Even today, one of the traits of classic autism is a seeming lack of interest in the world, or else a focus on small details rather than the larger world.
Thus, "Autism": Someone who is separated from others and the rest of the world, and focused on himself.
It's not a perfect description. It doesn't take into account how very intimately many autistic people are connected to their surroundings, and how intensely they may experience their sensory surroundings. It doesn't take into account that autistic children are as attached to their parents as any other child is. And it doesn't take into account that some of that "aloneness" that NTs see in autistics may simply be due to the lack of NT-style nonverbal cues, rather than a true lack of desire to interact.
Still--it's not so bad, as far as a name goes; and anyway, it's quickly growing to mean, more than anything, the spectrum of PDDs as we know them today.
