I’ll bite, I think your individual neurons are “just as” conscious as your whole body/environment system. They can’t advocate for themselves in words, but they have their own goals and interactions and decisions and needs.

Your aliens don’t know what it’s like to be you. But if these aliens decide to use your blueprints to print out a human, and the human says “ouch”, is it still the hard problem? This is what I don’t get.

Of course the music is different than just reading the score. A description of a process is not the process itself. We cannot know what it is like “to be” a bat but we also don’t know what it is like “to be” a spleen cell. Or the European futures market. Or a colony of ants, or the United States. These processes are complicated and intelligent, though not generally thought of having qualia. But I think it is only our hubris that differentiates the experience of an individual organism from that of our subsystems or supersystems.
