Slow down Elon... slow down..
1. Are the any laws of physics that stop us from creating AI ? Answer is No. Nature already built it so its possible.
2. Is it possible to improve AI significantly ? Yes, because if we can build AI, AI can build better AI.
3. How soon can it happen? Since the trend is exponential. It can happen within 100 years.
4. Is it good idea to start worrying about it now? Sure why not.
Of course, the demos (http://104.131.78.120) fail all the time because they haven't done the work to feed in the whole internet and handle proper names and stuff.

Some people think "well, it's likely to happen within 100 years -> it's up to us to be prepared".
Other people think "well, it's unlikely to happen within 10 years -> it's not worth it to begin to prepare".
I don't even know if one of those is wrong!
