> Capturing signals from you eye nerve doesn’t tell anything about your subjective experience of seeing an apple.

I strongly disagree. It actually does tell you quite a lot. For example, if there aren't any signals, you're very likely not seeing anything.

> The only way to understand that you’re seeing an apple from this signal is to train a model on your responses

It seems to me this contradicts your first argument. If such models exist (they very likely do, I'm not familiar with this area of research), they can tell us a lot about a person's experience.

Searched for “pholosophical zombie” but couldn't find anything, sorry. Just kidding :)
