It's not me saying that...but the ones in the "think tank" who worked in the most advanced (and currently still secret) technology programs, space programs, military programs etc....you have to detach to the general thinking and information available from the media if you want to get some of this information (well....just a glimpse), keeping a wide open mind and connecting the dots, it's a tough effort.
Just remember one thing, when some "expert" says something and tells "it's some years of research away", it means they are already there, even 20 years ahead with what they are speculating, it is always so and has always been so in the military research, one very simple example ? Oleds exist since 60's
What "they" show us is ALWAYS very old technology, 20 to 40 years behind, there is already perfect Holographic tech, more advanced that the one seen in Star Wars but they just still can't show us because it would totally reverse our paradigms and view of the universe, so they are just giving us drop after drop of anything "new", trying not to reveal the physics behind it.
Elon Musk said what he knew because he has contacts with people inside these think tanks (and he's of course a smart guy), and revealed they are already having huge problems controlling the same AI they thought they could use to their benefit, it apparently outsmarted them.
Agree in any case with you that it is an incredibly wide matter, covering almost every aspect of life on this planet, but I think it could be addressed always asking to ourselves "who controls who ?", and always choosing wisely all and any thechnology the industry giants are offering us, remember they always think in terms of profits (theirs) and nothing else...
