After successfully becoming the richest man, Musk left the Tesla factory and turned to personal interests.
On December 8, Tesla CEO Musk bid $7,753 for two assignments graded as a teaching assistant while studying at the University of Pennsylvania. The file contains Musk's handwritten initials "EM" and some notations.
According to auction company RR Auction, the assignment belonged to a student named Brian Thomas. He left no comments on Thomas's assignments, writing only the initials and scores of his name.
And Musk recently said on the Internet that I want to quit my job full-time as an Internet celebrity, which may be better for Musk to be an Internet celebrity to show personal charm and value.
