Yet C23 isn't K&R C any longer, nor is the hardware a PDP 11.
Also when we eventually start talking to agents that perform the whole execution steps by themselves, that is kind of irrelevant.
Except for the lucky ones that still code to keep the infrastructure going, which is mostly C++.
The PDP-11 myth is getting a bit tired by now ;)
If C would be so hardwired to the PDP-11 architecture it would have died with it. In reality C works just fine on all sorts of hardware (like GPUs) with only minor extensions.
The "nor is the hardware a PDP 11". Byte access was the main new feature of the PDP 11 that C adopted. Are you saying being able to access individual bytes is not relevant on modern hardware?
