What do you think about cryonics, mind uploading, transhumanism and digital immortality

I've been thinking a lot about cryonics lately, which is the freezing of the human body or brain in hopes that future reanimation will be possible one day. I've been reading about mind uploading, transhumanism and other things that would lead to digital immortality. Do you think these things will ever be possible and if so when? Also, does anyone think that in the extremely deep future (I'm talking millions, maybe billions of years from now) will it be possible to resurrect the dead using technology? I only want the opinion of people who are deeply into science, technology, futurism and physics.

Yes to all of the above.

2045: The Year Man Becomes Immortal

It is estimated that supercomputers will equal human intelligence by 2050 and exceed it thereafter

Extending the useful human life span is well within our capability right now, we just don't do it yet.

You might want to research 1. Human brain computer interface; 2. nanotechnology; 3. synthetic biology; 4. quantum computer capability

There is great progress in all of the above fields which will ultimately express themselves in the form of human extended life span. I have heard it said that people now in their 40 and 50's will just make it to the point where technology will be readily available for extending their lives.

Good luck

Silly sci-fi ...fantasy....impossible.....useless idle speculation
