"Any and all cost" would subsume low probabilities if it were true (which, of course, it is not).
I don't see how. To me cost is what you pay, not what you get. If the poll said "an unknown but probably extremely small chance of cybernetic immortality", then it could be comparable to cryonics.

The nice thing about Russians (I'm from that neighborhood originally) is that they are absolutely crazy and will try just about anything. They also probably have/had second-best science culture behind US (though they suffered significant brain drain as huge numbers of educated Jews left in the last 25 years). They have less regulation and quite a few rich people with ideas. Seems like a worthwhile group to keep in touch with.
