It's interesting that it was actually AMD that kept the Intel x86-64 architecture alive.
Intel knew that the x86 architecture was limited in time, and tried to kill it off with the the 64-bit Itanium.
AMD had a different plan, and released 64-bit capable x86 processors, obstructing Intel’s plans to dominate with Itanium. I think this is key to why Itanium never caught on, and why writing software for it is so hard.
