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.
What weapons? Exactly. Be more specific. You could speculate endlessly about some abstract unnamed weapons but you will never find a ways to circumvent or ignore them without switching to exact things.
Lack of concreteness is a cancer of conspiracy theorists and critical thinkers communities.
