Several weeks ago, Elon Musk, Peter Thiel and a number of other information technology sector luminaries created a non-profit artificial intelligence (AI) research organization called OpenAI which aims to develop AI while protecting mankind from rogue unfriendly AI led annihilation. While reading about that story, I came across a past photo from 2000 of Elon Musk (on the right) and Peter Thiel (link to WSJ article with photo here):
I was quite shocked to see his thinning hair, as I always see Musk with a full head of hair in all his recent photos. In 2000 he was just 29 years old, which means that he probably started balding in his mid-20s or perhaps even earlier. You can see more balding images of Musk in this video from 1999.
This is what he looks like nowadays per a Reuters photo:
