I understand your point, and your totally valid concern about nihilism, but I disagree.
Nihilism is "nothing really matters, science can't define good or bad, so who cares?"
Whereas my view is, "Being good is the most important thing, but we have no conceivable way to measure if we are making progress, either empirically or theoretically. We simply have to lead by example, and fight the eternal battles against dishonesty, cowardice, sociopathy, deception, hatred, etc."
It's in that sense that I say that technical progress is impossible. Of course, if everyone agreed with my view, and lived by it, I'd consider that a form of progress, but only in the sense that "better ideas seem to be winning right now," rather than in any technical sense of absolute progress.
