Strawman. Yes, liquid nitrogen requires energy to create. Cryonics facilities do not usually generate it but instead buy it, it's much cheaper than you would think. They have perpetual funds which the first failed Cryonics attempts did not. They do not cool refrigerant via electricity on site. I abbreviated this explanation because I thought it was obvious but apparently not. My point is the entire structure of modern Cryonics is not anything like what the article depicts, it's a strawman talking about 50 years ago. There is no magic and it's very unlikely to work but not 0. I would guess 1%.

I'm actually struggling to understand where you got the word "magic" from my description. It's possible my advanced physics training caused me to abbreviate things that are foundational, like entropy, heat exchange rates of a vacuum (e.g. observed in a Dewar). Are you interpreting something specific I said as incompetence or simply aggressively cherry picking my argument because of your own?

Most cryonicists are quite educated, but they are also fucking nuts so I won't argue that one lol.
