Apple also has hundreds of billions of dollars in reserve, which probably makes a bit of a difference.
Apple doesn't have the technical imagination to spend the cash it has on hand in the fashion Elon Musk and his talented C-suite teams have. Give Apple the last 10-years todo-over and they still fail to achieve half a Tesla or a quarter SpaceX or an eighth Starlink. The three combined? No frickin way. Apple's billions and billions of dollars will likely get spreadsheeted to the legal and accounting departments.
