Itanium was a huge business success for anything AMD64. I think IA64 was too early and targeted the wrong market too be a success of its own. Also being a single source ISA is very unattractive. If the ISA had been open like RISC-V, and the target market was scale out servers and small computers rather than the nonexistent scale up HPC market and almost nonexistent scale up database market, things could have been very different. On the positive side maybe some open source ISA can emerge using EPIC type architecture now that the proprietary version is dead.
