Been here before
I well remember the RISC anxiety at Intel when I worked there 35 years ago.
No one was under any illusion about X86 vulnerability and the perceived attraction of RISC.
Andy Grove, the founder of Intel, taught us that "Only the Paranoid Survive" and was not afraid to do whatever it took to keep the competition at bay.
Never assume that Intel doesn't recognise danger or is afraid to use its formidable powers to survive.
