What do you mean by secure? Actually impossible? An attacker needs more than $100B to breach it? $1B? $10M? In my opinion, if Jeff Bezos, Satya Nadella, Sundar Pichai, and Tim Cook all got together and wanted to put together a team that ship secure commercial software, they would probably be unable to put together a team that knew how to get to the $10M level, and there is zero chance at the $1B level. If they all worked together and put their full focus and resources on the problem, they might be able to put together a team that could invent how to get to the $10M level, but they would not be able to put together a team that already knew how and had experience doing so. The key difference between these two cases being that in the former the team would need to invent good practices and experiment to see if they worked, where as the latter only needs to apply already existing known good methodology. If you want some 3rd party evidence for my claims, not that I am claiming this is exhaustive proof, bug bounties that get claimed are, generally speaking, less than the cost of discovery for a bug otherwise security researchers would not put in the effort to discover than claim them. Not a single one of their premier products that they ship and sell [1][2][3] offers a bug bounty over $1M for total and complete remote zero-interaction compromise. It is very unlikely that they can do an order of magnitude better than the premier products just because they want to.
