I think the AI is the furthest away, though predicting where technologies will be in 200 years is basically impossible. IIRC TARS is able to converse with humans naturally (even telling jokes) navigate about as well as humans in a variety of climates and conditions. From a controls engineering perspective, This is a lot more difficult that it might seem react to emergency situations in an intelligent way (it was able to rescue one of the humans from an incoming tidal wave and carry them safely to the spaceship). I encourage you to check out the DARPA robotics challenge videos. The current state of the art allows our robots to (very slowly) navigate a controlled, known environment, and even then most competitors cannot complete the course. I agree with the articles timeline, I really doubt we'd see something like TARS in the next 50 years, but 100-200? we'll see.
