> Let's consider your proposed 8086 done in a 14 nm process. Let's say we do it in CMOS, and maybe even throw in a few extra features, and it takes 100,000 transistors. The die would be very tiny, so unbelievably tiny. You could fit three thousand of them, with room to spare, in a single square millimetre, which is an area likely smaller than the period at the end of this sentence.

Of course, you’d still need pins for power…
