[?] Why should Distros be called as i386 for a 32-bit PC, and as amd64 for a 64-bit PC, when Intel Core PCs are also 64bit systems

[Susmita/Rajib]

While Intel PCs are also 64bit processors?

For instance, my current laptop is Lenovo IdeaPad 320-15ISK 80XH01FKIN
15.6-inch Laptop (6th Gen Core i3-6006U/4GB/2TB/Integrated Graphics),
a 64bit processor.

It can't be that intellectuals, technocrats and cognitive elites
involved in the development of this complete OS+packages could be
misplaced in their perceptions. This is impossible.

So why such naming?

Could I be educated in this regard please?
