I could read about this subject all day. It's so interesting.
This isn't necessarily for you (although I'm sure you'll find it an interesting read). But anyone who doubts how quickly we will reach superintelligent AI should have a look at
this article.
This is the key sentence:
Because of the exponential growth (that we already see) in AI, we might see something that is 6 million times better than the currently most intelligent AI within 1 or 2 years.
Then something that is 36 TRILLION times more intelligent 1 or 2 years after that (The historic exponential growth in this area is faster than my example - so it's likely to be a much shorter timescale).
Superintelligent AI is around the corner, and anyone who can't see that is either uninformed or an ostrich.
Whether it will be good or bad is a completely different discussion - but feel free to bookmark this post. Within five years, AI will have changed our lives considerably more than any other 'invention'.
