It's at least 3 orders of magnitude lower than that: no one was recovered from that frozen state alive so far.
That complex technology is freezing human bodies in attempt to preserve it for the future.
Even if in the future recovering technologies work - non-working first step (freezing) which is done today - will kill overall process.
I also qualified my original statement by saying that I'd do it if the technology improves. Extrapolating from past life expectancies, there is nearly a hundred years for the technology to develop until I need it. Saying the technology won't be there in a hundred years is a very strong statement.
2) You are extremely optimistic. Life expectancy improves for about 1 year in every 5 years (I'm quite optimistic with that estimate too).
So if you are 30 now, then by the time you are 80 life expectancy would change from 78 years (today) to 88 years(50 years from now).
So basically you have about 60 more years to live if you are lucky.
No way that freezing technology would improve into something meaningful by then.
