Your basic logic is lacking.

"Humans are animals" and "Some animals have four legs" are both
undeniabvly true.

That still does *not* mean "Humans have four legs".

And yet hat is *literally* the kind of nonsense you are spouting.

I very much say that "some devices will not have UUID's".

That's a *FACT*.

You then say "Some devices have UUID's, so all devices must have UUIDs".

That's *STUPID*.

Can you really not tell the difference?
