These arguments probably trace back to the pitfalls of Von Neumann architecture, and the hardcoded expectations of memory and such. It would require experts in very disparate fields (mechanical / electrical engineering, computer engineering, software development, theoretical mathematics, and others) to develop a viable replacement. I do postulate that we are already kind of warping that model, though. SMP and NUMA force you to question the assumptions and that lead to a lot of the modern changes of tone (functional programming becoming big because asyncs and lambdas are really useful, for example).
