My girlfriend/SO's grandfather died last night, running on a treadmill when his heart gave out.
He wasn't signed up for cryonics, of course. She tried to convince him, and I tried myself a little the one time I met her grandparents.
"This didn't have to happen. Fucking religion."
That's what my girlfriend said.
I asked her if I could share that with you, and she said yes.
Just so that we're clear that all the wonderful emotional benefits of self-delusion come with a price, and the price isn't just to you.
Vitrification works in organs. Neurons are being simulated in software. Stem cells tech is improving. We already pretty much have the electron-microscope and chemical assay tech to dice, slice, scan and digitize a frozen brain. We don't yet know exactly what to digitize, but neuroscience is a heavily studied field.
The fact of revival isn't here yet, but the peripheral evidence is strong.
You may be surprised, but none of these arguments significantly move me. I think that damage is too great and complex for such techniques to work for a long time, and when something will finally become up to the task, the particular list of hacks you mention won't be relevant at all.
