It will be very nice to have a comprehensive list of possible so called "disruptive inventions" or "closing inventions" i.e. such inventions that destroys industries and can do a lot of harm to corporations or states.
as kickstart, order means nothing:
- antigravity
- neutrino beam communications
- force shield
- electricity accumulator with decent power density (orders of magnitude larger than current lithium crap) and reliability
- FTL travel
- high-efficiency fuel powered electricity generator without moving parts
- atomic level 3D printer/copier
- inertial mass control
- simple consumer-grade fuel converter (organic compounds to gas/diesel)
- plants growth speed accelerator
- useable way of making building materials (blocks/bricks) from any soil. ....
Please continue.
I think you and I have a disagreement on what we mean by "immortal" with regard to cancer cells. Whatever.
As for billions to spend, I would say it's a question of priorities. Man would have a moon base now if America didn't spend so much on black people. That's the problem with tax dollars, they go to short term priorities.
Frankly, if we are ever to get effective anti-aging treatments, it will come about because irreligious assholes like these guys fund it: https://www.cnbc.com/2021/09/21/silicon-valleys-quest-to-live-forever-could-benefit-the-rest-of-us.html
I personally don't think that endless immortality have any sense, especially from religious side. I believe that humans are more than body, and body isn't what constitute human, at some point we have to move forward. However it could be useful to enhance the period of healthy life. Humans usually acquire wisdom when their bodies already weared, so a lot is lost. Bible mention that humans lived hundreds of years so this goal should be fine even from religious point of view.
Oh, it would be grand if we had more years with the health of a 20 or 30 year old body. In many way, we've got great advancements that make being in your 70s more like the 50s.
But death comes for us all, I agree. The people who lived a long time in the Old Testament weren't as corrupted, and God chose to lower lifespans at a point.
