"But all you've done is built a robot. You can't prove it actually has experience - including self-awareness - unless you can measure experience with objective instrumentation."

We build things all the time based on the models of the universe we've got. Your argument strikes me as more or less saying, "sure, we built that jet engine, but unless we can measure what 'being a jet engine' is we've just not really built the complete, real thing."

If we build a thing that appears to have "experiences" indistinguishably from how humans appear to, then that is it. That is, the notion of "experience," as you describe it, is more or less meaningless in the context of the very physical world we occupy.
