The complexity of Intel processor, chipsets, and board-sets is, I believe, the most complicated and difficult engineering in the world. Once every 20 years, Intel drops a bad-bug-bomb that gets some public notice. Even the FDIV bug was already fixed in-house when the public discovered it under the most non-real-world conditions. It was even discovered before the first R0 went out the door. However, because of the FDIV bad publicity, Intel worked in microcode patch mechanism. And that legacy will fix this "problem".
But, Microsoft, Google, Apple, ... whatever software... just gets away with bugs upon bugs upon... "we'll issue a patch".
Yes, Intel spends BILLIONS a year making sure shit works. And with BILLIONS of parts, some slip through, and, in the real-world, don't cause any problems whatsovever, unlike the SW companies heretofore mentioned. We just expect shlockware from software companies.
