I have this question too.
That said, I have the same question about cemeteries... why would anyone choose to keep devoting increasingly valuable real-estate to storing my moldering corpse?
Of course, I don't care so much about cemeteries... I endorse them getting rid of bodies once nobody who cares about that body is going to visit, as long as they aren't fraudulent in the process.
Then again, it does seem that individual graves in cemeteries do continue to exist long after there's any reason I understand for them to, so it seems that there are more factors in play than I'm considering... perhaps a simple metonymic respect for the dead?
Which might not manifest in the same way for cryonics... and then again, it might.
Careful, someone else just gave me the "dumb question" lecture. For what it's worth, I think your analogy is the right line of inquiry. I agree that the two analogues (cryogenics and burial) aren't strictly analogous though, cryogenics does take more resources.
For what it's worth, here's what the Cryonics Institutes gives in (their FAQ)[http://www.cryonics.org/prod3.html]:
...Q: Why would people in the future want to revive us?
A: Why are scientists talking about cloning from the DNA of the pharoahs or the frozen sperm of prehistoric animals? Bec
So, apparently appsumo is having a custom reddit bundle, a bundle meant to appeal to redditors, and 10% of the proceeds get donated. On the surface, doesn't sound _that_ interesting, except...
Take a closer look: http://appsumo.com/reddit-special-deal/ and find that the recipient of the donations will be... SENS!
I find this to be an interesting development. It wasn't the "custom transhumanist bundle" or "the custom sens bundle" but "the custom reddit bundle". Yes, "reddit" doesn't, in and of itself, count as extremely mainstream as such, but I'd say it's still an interesting development.
