i'm not 100% well informed (=0% informed) about the differences
between cache and RAM.

but i dare to bold-guess that cache can grow to eventually eliminate
the need for anything else.

i don't know about that, i'm not the NSA, and i have more than 200,
well okay, not cores, but pipelines in my pc. but that is what i see
in the future. CPUs don't have to be smart, we have smart compilers
instead. in fact, i believe compiler writers would thank for simpler
instruction set, so they could have simpler optimizers. so what if the
GPU approach eventually wins? i'm no expert though.
