Suppose Elon Musk (born June 28, 1971) is a business magnate, industrial designer, and engineer. He is the founder, CEO, CTO, and chief designer of SpaceX; early investor, CEO, and product architect of Tesla, Inc.; founder of The Boring Company; co-founder of Neuralink; and co-founder and first engineer of PayPal.
Can we infer that "Musk has only founded one company in his career."? Yes, no, or maybe?
