The point is, anything there is code speculation, virtually every single time they invent a new way to speed up performance, a new method of attack gets found. It doesnt matter if its Arm, it doesnt matter if its Apple, jt doesnt matter if its Intel, doesnt matter if its AMD, everyone has exploits as long as code speculation is a thing. If security is a severe issue, would the solution not be finding or using phones without code speculation period as as long as long as it exists, historyically speaking, its only a matter of time till an exploit exists for it.
