To an entity without a phenomenal field, novel
behaviour will be phenomenally invisible. Everything
will be phenomenally invisible. That doesn't
mean they won't be able have non-phenomenal
access to events. Including novdl ones.

That's a claim -- that any projection from internal sense-data to a
hypothetical
external source is necessarily phenomenal -- not an argument.

Not necessarily. AI researches try to generalise as much as possible.

You pass easily from "humans are connected to the external
world phenomenally" to "no entity can be connected to the external
world except phenomenally".
