> At some point, we'll have AGI that pass any test we can think of and we'll still have people arguing that these cannot be conscious.

You've already drawn your line in the sand (i.e. they are conscious). In that case, you can't also claim that we should continue producing them by the millions at the flick of a switch.

The AI-is-conscious crowd will have to choose - either they are conscious, in which case they should not be birthed, or they are not conscious in which case we can use them as tools. You can't have both and still be logically consistent.
