We are not close to westworld yet. Closer on the bodies than the minds. There is a danger from Expert Systems, but the danger is from less sophisticated things than the Androids of Westworld.
They are overselling these things. They are not as sophisticated as they are making it out to be.
Yes the D-wave machine seemed to be a bit of a half-way compromise with true Nano-tech. I don't think anything can be said for certain as they lock up details for 100's of years or purchase tech and copywrite it so it never gets to the mainstream.
I totally agree with the "overselling" thing. They have to in order to make it appealing to us all. We simply don't get given good things by 'big-bro' and over-population is just another disguise for replacing us with much more economic models.
