If "level" is ill-defined then low and high aren't relative terms, they're meaningless. But there is a lowest either way, the machine code. Then high level programming languages have the programmer writing code in a model independent of machine architecture. Those models are't one dimensional, so let's not bother trying to put them in order from low to high, let's talk about their features.

That's how i'd have it if it were for me to decide, but this isn't how language evolves.
