No confusion here, Cecil. Wouldn't such a statement be considered by
most to be ad hominem, i.e. about the person, rather than about the
subject being discussed? You accuse people of doing it to you all the
time, but never seem to be able to fess up to it yourself.

Once
again, AC current changes direction every 1/2 cycle and the sign of
the cos(phase) function determines which of two, and only two directions,
it flows.

Why do you keeps saying the sign of the _cosine_ of the phase determines
instantaneous direction? That's no more true than saying the sign of
the sine of the phase determines the instaneous direction. It could in
fact be completely untrue.

Current is NOT a vector. Current is a phasor with two and only
two directions in a wire.

According to definition, current is a rate. That should be obvious from
it's units of coulombs per second. Alternating current can be expressed
as a rotating vector, or phasor.

Your phasor current "phase" is only an imaginary
math function, a crutch to make the math easier.

Are you talking to me? Helloooo.

One amp at 90 degrees
exists in your head, not in the real world..

Methinks that conversation must exist only in your head, Cecil.
