Not really when you think about it. CPU instruction is a bytecode 
like another, with provided hardware interpreter for it.

It is becoming common to have VM not going through the 
interpreter step (ie software interpreter) to go directly to low 
quality but fast codegen. V8 is doing this for instance.
