> Why do you need a subjective first person experience [...]?

I reject the premise that I need a subjective first person experience. I don't have a subjective first person experience.[0] I have convoluted, poorly-documented internal data processing mechanisms cobbled together by a blind idiot over millions of years. These could, in priciple, be measured with sufficiently good instruments.[1] They could, in principle, be analyzed and translated into a form compatible with someone else's spaghetti-coded wetware. I don't have a subjective first person experience; I have a objective first person experience.[2]

0: And neither do you.

1: And this is likely to be feasable in the next couple centuries.

2: Like a p-zombie.
