Late last year, he was promoted to Vice President in charge of the complete Optimus program, as CEO Elon Musk began to tou t the program as critical to Tesla’s future. Musk claimed that Optimus could generate $10 trillion in revenue per year and make Tesla a $25 trillion company. These claims are largely unsubstantiated as the humanoid robot market is still in its infancy. Most market research firms currently estimate the size of the humanoid robot market to be in the low single-digit billions of dollars, with growth projections through 2032 ranging from $15 billion to $80 billion. That would represent impressive growth, but nowhere near what Musk is touting to investors. Today, Kovac announced that he is leaving Tesla for personal reasons: This week, I’ve had to make the most difficult decision of my life and will be moving out of my position. I’ve been far away from home for too long, and will need to spend more time with family abroad. I want to make it clear that this is the only reason, and has absolutely nothing to do with anything else. My support for Elon Musk and the team is ironclad – Tesla team forever. Kovac has been regarded as one of the top new technical executives at Tesla, which has seen a significant talent exodus of top engineers.
