Review of state-of-the-arts in artificial intelligence with application
  to AI safety problem
  Here, I review current state-of-the-arts in many areas of AI to estimate when
it's reasonable to expect human level AI development. Predictions of prominent
AI researchers vary broadly from very pessimistic predictions of Andrew Ng to
much more moderate predictions of Geoffrey Hinton and optimistic predictions of
Shane Legg, DeepMind cofounder. Given huge rate of progress in recent years and
this broad range of predictions of AI experts, AI safety questions are also
discussed.
