In a nutshell, the useful fiction of computer-as-Von-Neumann-meaning doesn’t adequately reflect the reality of modern hardware. Not only does the CPU itself not fit that model (with things like speculative execution, sophisticated power and load management…), but the system as a whole is increasingly an amalgamation of different processors and address spaces.
