Elon Musk is best known for his work with Tesla and SpaceX. He is known for being a part of the EV revolution by attempting to push for cleaner energy using everyday drivers, commercial vehicles, and even working on an electric airplane. He even claims to be open to merging with other automakers.
Something Musk has been known for recently as well is taking to Twitter to promote and shed what he feels is honesty regarding the Tesla line and its competitors. With his extravagant and sometimes questionable designs, such as his 37 engines used to travel to space and the design of the cybertruck, he is quickly placing his mark on the world.
With Elon Musk reportedly only owning 20% of Tesla, he has a significant stake in the company and seemingly has a lot of influence on what goes on. Elon Musk feels that Tesla cannot run without him, and he may be right. He has pushed technological advances considerably since his involvement and continues to do so every day.
