Yes, I agree it's non-zero. It's a (1. benefit) x (2. probability of benefit) / (3. cost) type of reasoning, and both (1) and (3) are subjective, so everyone can choose for himself whether "it's worth it" or whether you want it.
I'm just emphasizing that this technology is not a realistic solution to anything, just as a lottery ticket is not a solution for one's financial problems. I may choose to buy a lottery ticket myself, same as I may choose to have my head frozen, but I'm not going to consider this as a real solution to any problem - just like a lottery ticket, it may have more "entertainment" value than real value (though the "entertainment" value may be enough for me to buy it).
My only point is that we should always see the difference between "lottery tickets" and real solutions, and always see the former as what they are: hope growing "entertainment" forms... I know, most people don't like this way of looking at things and label it "dark and gloomy", but it's how I see it :)
The difference is that people win lotteries every week, and so far no-one has been frozen and thawed.
As we're using analogies: we know that machine-flight is possible. But how many people broke their legs after gluing feathers to wings strapped to their arms and jumping off a barn, flapping wildly, before Kitty Hawk flew?
