It’s not that free radicals are good (they are necessary, but excess free radicals are definitely bad), but more so that there is no solid research to suggest that dietary antioxidants have any effect whatsoever. All the studies that show any beneficial effect have been shown to have major flaws or have not been able to be reproduced consistently.

It’s more complicated than good or bad. High levels/sustained stress are definitely bad, but there’s some research to suggest that short-term oxidative stress is an important trigger for various responses in cells.

It opens the run dialog, which I’m sure the vast majority of Windows users have never heard of. This would trick a lot of people who just trust whatever their computer asks them to do.

It’s hard to run any Unity/Unreal game in 4k on my 1070

Both of these engines are capable of making very optimized games, it’s just that most of the developers using them either don’t have the expertise or don’t care to put in the effort.

Which, again, is an incredibly unlikely attack vector unless you have some government secrets on your computer. And chances are that any attack through the IME or PSP is trying to do an implant into the UEFI/BIOS and not the processor itself.

CPU firmware exploits are incredibly rare, if there even are any that exist beyond proof-of-concept. The chances of getting an infected CPU from this is so unlikely it’s practically impossible.

If I understand it correctly, the chip has the vulnerability, but the malware would be installed on the motherboard in the form of a bootkit. So getting a used CPU is not a threat, but getting a used motherboard is (and kind of always has been) a risk.
