1. Nuclear fusion economically viable
Hopefully just in time to replace the dependence on fossil fuels before it becomes too much of a problem
2. Hydrogen fuel cell technology widely used
To replace all fossil fuel needs in moving vehicles
2b. Miraculous breakthrough in battery technology
Maybe something coming from carbon nanotube technology, alternative to the problems of building a hydrogen fuell cell based economy.
3. Quantum computing
This will speed up a lot of research in science, especially in genetics and curing diseases.
4. Mind computer interface
You hear that inner voice in your head, what if you could instruct/reason with a computer just by thinking of talking/reasoning with it.
