I'm imagining the way to go would be to evaporate the liquid in the first tank, then pump the gas from one tank to the other one, like you would pump any other gas, and then liquifying that gas to liquid again.
You would probably agree, then, that such material is not problematic, because even if it looks like CSAM, and it quacks like CSAM, it is not CSAM, therefore we don't have to take it seriously or regulate it in similar ways that we do regulate actual CSAM, if I continue your logic, no?
I believe that at a certain point, "agency" is an emergent feature. That means that, while all the single bits are well understood probability-wise, the total picture is still more than that.
It makes sense to me to accept that if it looks like a duck, and it quacks like a duck, then it is a duck, for a lot (but not all) of important purposes.
I disagree. This is no meaningful talking point. It doesn't help anyone in practice. Sure, it clears legal questions of responsibility (and I'm not even sure about that one in the future), but apart from that, making an artificial distinction between a human and a looks-and-acts-like-human, provides no real-world value.
Yes, happens a lot. I would be very surprised if the brain had no nerve endings at all, given that almost all human tissue has nerve endings in it (except hair maybe).
I guess what you feel is a complicated mixture of:
The Fuck operation, also known as dual pairing.
