It's not even that, it's "common programming languages and programming paradigms do not always enable you to exploit this". IE if everyone is writing sequential C++, making a chip that is really good for parallel fortran is .... silly. No amount of compiler advance would have saved itanium. Research early on shows except for very contrived kernels, there wasn't enough ILP to extract. It actually did a really good job of doing what it could :)
