It doesn't get us anything at all other than a fucking huge rabbit hole to stare down every time you do anything. Lets look at a pretty naff case for .Net CLR on x86 for windows workflow:

application -> xaml -> framework -> server -> container -> c# -> cil -> bytecode -> x86 instructions -> microcode.

Now forth on a 68000:

Forth screen -> 68k instructions

To be honest, for what I consider to be life and death stuff, a 10MHz 68000 is good enough (I have one in my TI92 calculator).
