I believe the chance that anyone who is cryopreserved today will ever be revived is exceedingly small, so I look at the whole venture as futile and in the same way I might look at an overly expensive funeral. Personally, I would spend my money to enjoy my life more while I'm alive, or else to help others in some tangible way.
Actually it is important tech for living people as well. The technology De Greg Fahy is working on can be used to freeze and unfreeze organs. It may save your (living) life if you get an organ just at the right time.
