Flight of thought

Please do not take this topic seriously, I just wondered the opinion of others. Because I propose to dream
Technical progress is increasing exponentially, every day something new appears.
Four years ago, I sat on the 7th wolf and watched which games would come out in a month, two, to know what to prepare the computer for.
Now it is useless, by the time the game on the market everything has changed.
This applies not only to games.
USB 3.0 is coming out soon, an 80% nuclear percent was invented (I was not sealed)
Growing all that is possible.
In connection with such an increase in capacities, I wanted to ask the Habrovchan opinion as direct participants in scientific and technological progress (just do not say that I re-read fiction, development and testing is being conducted and, moreover, many are successful):
1. How many years are left to full-fledged nanotechnology (chips in the brain, tissue repair, etc.)
2. When will we fly into space?
3. When will invent a full-fledged AI?
4. In how many years will this AI kill / make an attempt to kill all of humanity and will it happen at all?

Threat Once again, I do not take this questionnaire seriously.
