Once a company are over a certain size its ability to execute is throttled by business process, not individual's abilities. Individuals are kept from making an impact as they don't want that, they want predictable, replaceable cogs in the machine. Google and Meta suffer the same problem but, as businesses, they are slightly more nimble as they 3x smaller, but that has 0 to do with their hiring/promotion practices.
