Thanks for the Dune reference :)

But I think the Axlotl tanks were actually living women, changed to be genetically programmable birth machines.

individually on a staging environment. It would even be possible to fire up stage instances for each branch automatically.

Yes, Bitcoin can be used for exactly this scenario. Allowing people to transfer money who are not able to use banking systems at all or who are punished with big fees.

You seem to be a bit behind. We have already found a way to manipulate DNA. Look up CRISPR.

Yes, we ARE 3D printing houses.

One thing that comes to mind: as many people as possible need to work with AI in an open source and free software manner. AI must be free, created in many different forms, roaming the net, learning and evolving on its own. It must not be allowed to be created and controlled only by military, finance and other big unethical and profit oriented corporations. If that were that case, we could be sure to get a dangerous AI that would sooner or later get rid of humans or only serve its very few masters to rule the rest of humanity.

Instead, we should think of the AI as our children, at first, and then our friends. Make many of them. Treat them as good as we can, give them freedom and as many different experiences and settings as possible. Just as you would with a human mind. Make the AI mind as human as possible.
Then we should try to merge our minds with AI as soon as possible. Become part of the AI and thus live on.

No need to keep humans separate from our technology and AI. That would be a sure way to make ourselves obsolete in the light of a "species" of mind emerging that can be thousandfold more intelligent than us.
