  • Elon Musk rejects the label of 'investor' and says he's not Warren Buffett in a new tweet.
  • The Tesla chief sees himself as an engineer and innovator, not a capital allocator like Buffett.
  • Musk and Buffett have clashed in the past, but both men have praised each other as well.

Elon Musk has drawn a line between himself and Warren Buffett once again, underscoring that he sees himself as a builder of businesses and products, not an investor.

"You have the 'invests in Tesla' part wrong," he replied on Sunday to a tweet summarizing his career path. "Do I look like Warren f* Buffett to you?"
