I think we should all plan for a defense against terrorists targeting people who want aging to be cured, specifically scientists who are working on it.
Why? It is because when it is shown you can extend healthy life in mice by a very great amount, some low life, bio conservative, religious fanatic, terrorist organization or whatever will probably come over and shoot Aubrey de greys brains out, and bomb and destroy all the research done on developing anti aging therapies. And they would probably come to Al cor and bomb the cryonics centre
It is just a potentially real possibility I would like to point out. I would hate to see that when there is finally life extension therapies it gets ruined by not enough careful planning and preparation to protect the Life extension cause.
Currently I don't think we face any threat. But in the coming decades when breakthroughs occur, and even more importantly: life extension becomes socially acceptable than there will definitely be opposition.
If there are
Immortalists than there is no doubt that there are
Amortalists out there. Amortalists strongly believe that it is socially destructive for people to live forever, as this can result in a stagnant, ultraconservative society dominated by individuals concerned only with continuing their own lives.
Amortalists activists will attempt to influence legislation to oppose (for example) state-funded health care planes that will include provision for expensive or mass longevity treatments.
Example of modern day political activists:
Leon KassAnti-Technology Terrorism:
Theodore Kaczynski,
EcoterrorismThere will also be Amortalists who include religious groups who believe secular immortality is against God's plan or defers heavenly rewards. These include many groups but primarily will be radical Christians and Muslims who already show evidence against science and technological progress.
See also:
Primitivism,
Neo-LuddismAnd of course you have a whole bunch of
conspiracy theorists against transhumanism too.
Personally I divide such opposition into two groups: Right Wing Bioluddism: oppose immortality for traditionalistic and religiuos reasons.
Left Wing Bioluddism: oppose immortality for environmental or social reasons.
How to deal with future threats: I don't know; use secrecy or extra security?
However, with an opposition movement growing, there will also be another extreme imo: Cybergnostics.
Cybergnosticism is an extremist form of transhumanism. This is the belief that the physical world is impure or inefficient, and that existence in the form of "pure information" should be pursued. Just speculating now, Cybergnostics would probably be heavily dependent on technology, supporting destructive mind uploading (brain is destroyed in order to be scanned online) and cyber-terrorism, believing such views that "impure beings" have no place in their dreamed technotopia. Cybergnostics also includes theists wanting to reach/become God through the advancement of technology.
Overall, in the coming decades and centuries we will have a lot to deal with. But till then we have a long way to go before these technologies actually become a reality.
