99% of [people], but especially the brilliant/well known ones [in any domain], are insufferable egotists.
IMHO this is normal. When somebody puts in a lot of effort in mastering something they intrinsically know that they are better than most people in that something. As social animals, getting "noticed" is a form of being conferred "status" in the group. Thus you tend to "act out" to acknowledge/confirm that recognition. It is fine as long as it is within acceptable social bounds and not out of touch with reality.
