Why would "embed software in chips" be a solution?
If anything, I'd expect it to be an even bigger risk, because when (not if) a security issue is found in the hardware, you now have no way to fix it, other than throwing out this server/fridge/toothbrush or whatever is running it.
A flashable secure enclave segment in the hardware stack is an option to patch around embedded bugs.
I haven’t worked in hardware design since the era of Nortel, and it was way different back then but the general physics are the same; if, else, while, and math operations in the hardware are not hard.
In fact your hardware is a general while loop; while has power, iterate around refreshing these memory states with these computed values, even in the absence of user input (which at the root is turning it on).
Programmers have grown accustomed to being necessary to running ignorant business machines but that’s never been a real requirement. Just a socialized one. And such memes are dying off.
