It took many years for the "Wide World Web" to become a reality when it was suggested to be at hand for the latter part of the 90's and early 2000's. While e-commerce did close a lot of brick & mortal stores, it really was the phone that harmed our collective society the most.
Facebook and social media was supposed to bring people together and it did for a few years. Now, not so much. Evil doers realize they can manipulate the useful idiots - even though TV and Radio was doing a good job of it before the phone changed people's habits and beliefs.
Bill Gates stated that he erroneously believed that the infrastructure of cabling and routing of data would quickly come to fruition, but it took far longer than he originally professed it would. He also predicted that the internet would be able to fend off misinformation. Oops.
The lapse of a lengthy time for technology to come to fruition would seem to put us in a similar situation now. The power is not even in place to support the most consequential mechanisms of A.I. - deep learning & expert systems, etc. Gonna need a bigger power grid...
Likely A.I. will end up being rolled out at a slower pace than advertised as there are a number of sticking points that come into play with these massive energy sucking systems that will impart havoc on communities, local politics and laws.
One thing is for certain..Wall Street is betting big on it. But they will be hamstrung if the economy goes south for awhile, so none of it may be as imminent as we may expect.
