I agree in the sense that answering "what really are qualia" may be as impossible as answering "what really are quantum fields". At some point we may be forced to accept "it just is", but that doesn't mean we can't make meaningful progress first, just like in physics.

For instance, either new physics is involved or it isn't. Finding solid evidence for or against it does not seem impossible, and it would definitely constitute meaningful progress, at the very least by ruling some theories out.
