There are Harvard architectures - separate program + data - e.g. Nvidia GPUs supporting modern C++.

Also it has different memory spaces with its own pointers, e.g. shared memory (up to 228 KB), constant memory (64 KB pages), global memory (beyond 32 bits)

If I had been on the C committee back then, I would have supported the
support of these strange computers.

But today in 2025, C++ is being held back by the notion of computers
that have gone extinct. Now we should just make all data pointers
equal (or perhaps even go a step further and make function pointers
equal to data pointers too -- because I don't think there's a C++23
compiler alive nowadays that has different size data and function
pointers).
