@Phantasm adding to that, x86 has survived and thrived not because of Intel but despite of them. Basically, other vendors have forced Intel to stay in lane and continue with x86. IBM saved them from bankruptcy by buying their 8086 for the IBM PC after iAPX432 drained Intel's funds, then came them competition from AMD, Cyrix, and other vendors, forcing Intel to continue. If Intel wasn't going to make x86, someone else would've, as it happened with AMD64.
