| In a very low-level sense, you are correct. Objects have a lot to do

Thanks, I actually use things like this in my 'application-string-
interpreter', where user defined variables can have any format, including:
colour, location, input limit ranges, output form, array index etc..,
as tokens in any order. But this is a BASIC-like HLL-interpreter.

For pure ASM (talk to CPU) I know only a few possible datatypes,
exactly the types the CPU knows, and here I can't see any sense in OOP.
