1. Nuclear fusion. Near limitless cheap energy
2. Fantastic battery technology to take advantage of said energy (I would go the solar route if I had more than 50 years)
3. Moves to set up perment moon or mars colonies
4. Self driving flying cars
5. Star Trek style conversational computer
I don't really want virtual reality gaming, it then becomes too real and I feel there is a point where I don't want to be doing thinks like killing once it becomes too realistic
I have also left out the more social things, like better healthcare and less poverty etc, since that has less place on a gaming site
