Intel ARM AMD types are flawed by default making possible system attacks.
They went to develop patches in purpose to prevent memory corruptions even with the price of a lower processing speed - average of performance loss.
The problem of these patches were coming with an advice: Do not Install them - Intel patches. Why ? Because now memory is not read with 128 kbps or such (if I remember correctly) the flaw went to screwing with a few GB/s by directly writing in memory all kinda funky stuff.
Actually Linus Torvald - the creator of Linux was complaining about solutions and... he was not that happy as I could figure in that public debate...
Machines used in important domains will have security holes by default. Now let me know how goes privacy things in such case, Banks. Hospitals, Various Sales, etc, etc. I would not allow my life to be managed by a computer - like an old man said and he said well.
