> Don't forget it's not just instruction sets; Intel is the reason we don't have ECC RAM on desktops. Every other high density storage technology has used error correction for a decade or two, but we're still sitting here pretending we can have 512 billion bits of perfect memory sitting around that will never go wrong, because Intel fuse it off on desktop chips. I guess only servers need to be reliable.

And not just storage - the main memory bus is the only data bus in a modern computer that doesn't use some form of error correction or detection. Even USB 1.0 has a checksum. So everywhere else we use ECC/FEC or at least a checksum, be it PCIe, SATA, USB, all storage devices as you mentioned rely heavily on FEC, all CPU caches use ECC. Except the main memory and its bus. Where all data is moved through (eventually). D'uh.
