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.
That's why it is important to know what will possibly break that stupid path.
Technology can't be prohibited. Look what happened with mp3 or torrents. All corporations connected with entertainment industry spent enormous efforts to stop that, from stupid ads like "downloading mp3 you downloading communism" to legal punisment of those who was caught using that new tech. But nothing helped them. People clearly win.
