    Intel should be leading the charge in bringing out parts that are immune to these exploits.

    I am wondering about one thing. According to the press, Intel has been informed about the bug in June 2017. However it released new processors on October 2017, knowing that these processors are indeed affected and that fixes are at best semi-possible to fix through firmware and software patches.

    This is bad.

    I think it goes deeper. INTC management had to know this was possible, but used it as a shortcut to overcome architectural flaws in x86. By running without the seat-belts others provided, they could claim performance advantages and win in the market with no concern about the long term impact on customers. Even if they "get away" with this, they have lost all credibility with smart (cloud) customers who will back away and stop doing business with them. Maybe they will open source their own general CPU design that is more modern than this mess. POWER? Beyond that, imagine using any INTC chip in a car!

    From my understanding, this is not an ISA issue (i.e. x86 specific) but an implementation/architectural issue. I am wondering, are all the performance-impacting fixes be applied equally to all processors no matter if they are vulnerable or not? I mean if an AMD processor is not vulnerable, will the patches be applied to it as well as part of the fixes that OS providers will roll out? If this happens then others will be more screwed than Intel.
