There seems to be rather a lot of information lost beyond the chance of recovery.
Not if there are AIs out there in the universe who can catch the information and run it back to your FAI at lightspeed. And since our FAI can catch information about the causal past of other AIs that they'd otherwise never have been able to get back, it's even a clear-cut trade scenario. I see no reason not to expect this by default. (Steve's idea; I think it's pretty epic, especially if the part works where the AIs collectively catch all each others' quantum entanglements which enables them to coordinate to reverse the past. That'd be freakin' awesome. And either way, I think hearing this idea was the first time I thought, "wow, if a mere human can think of that, imagine what ideas a freaking superintelligence could come up with".)
What is the recommended literature related to the ideas both you and wedrifid have been discussing in this thread? I googled but I figure it wouldn't hurt to ask either. Thanks.
What looks, at the moment, as the most feasible technology that can grant us immortality (e.g., mind uploading, cryonics)?
I posed this question to a fellow transhumanist and he argued that cryonics is the answer, but I failed to grasp his explanation. Besides, I am still struggling to learn the basics of science and transhumanism, so it would be great if you could shed some light on my question.
