So say something about it. Your whole comment is an attack on 1, but regardless of his word on whether or not thing slice vitrification is currently the best we can do, we KNOW fracturing happens with current brain preservation techniques. Liquid nitrogen is well below the glass transition, so fracturing is unavoidable.
Why should we expect fracturing/cracking to be 1 to 1?
If you’re worried about the effects of cracking, you can pay for ITS. LN2 is only used because it is cheap and relatively low-tech to maintain.
If you ask me it’s a silly concern if we’re assuming nanorepair or uploading. Cracking is just a surface discontinuity, and it forms at a point in time where the tissue is already in a glassy state where there can’t be much mixing of molecules. The microcracks that form in frozen tissue is a much greater concern (but not the only concern with freezing). The fact that vitrified tissue forms large, loud cracks is related to the fact that it does such a good job holding things in place.

What’s “ITS”? (Google ‘only’ hits for “it’s”) How much more expensive is it? Is it offer by Alcor and CI?
Short for Intermediate Temperature Storage.
Oh ok. Thank you.
