It's like the first computer of the 1960s... massive and only available to big rich businesses 'cos it's cost is in the millions. It's the super power behind the concept known as "artificial intelligence" (AI), the thing that drives fear into the crazies on the far side, those who think there are lasers in space that probe human thoughts.
In this video, renowned physicist Michio Kaku explains that quantum processes really mean deriving energy and data from the atmosphere which allows supremely fast processing and greater productivity. He states that AI is harmless, despite the scenarios imagined by the movie buffs and the whakos that believe the Earth is flat. Just go with the flow and adapt and adjust.
