Apple would not exist.
Google would not have android as part as their Berhshire Hathaway-esque portfolio of technologies/companies. They'd have still beaten Microsoft in the search engine business.
Somebody would have killed Bill Gates or at least tried to, like it has happened with many POTUS. The person who is perceived as #1 will get all sorts of lunatics after them. (You could argue that is a safety system that nature installed in humans in order to avoid one person to monopolize decisionmaking) . Kinda like a more severe and irrevocable DOJ.
