I don’t know if you’re asking rhetorically or not, but the honest answer is we don’t know yet. Those sensory experiences are called “qualia” in philosophy and cognitive science and they are not well understood yet. You might enjoy the paper “What is it like to be a bat?” https://warwick.ac.uk/fac/cross_fac/iatl/study/ugmodules/hum...
Yes, it was rhetorical in an attempt to get the point across. I try to refrain from naming qualia when first explaining it. I've read Nagel's paper, but I haven't thought about it for some time so thanks for reminding me.
I usually see the Turing Test as a thought experiment for showing the irrelevance of qualia for AI, among other philosophical objections (e.g. Chinese Room).
