Hi! Piotr!
This is indeed a very interesting study and, I am very much elated that AI these days can now process data faster within 3 months. Now, I am not going to go through the whole TERMINATOR drama wherein humanity will be eliminated since robots and computers are now smarter than us.
As mentioned in the video, processing chips will be cheaper which in turn will make whatever computer/electronic based device cheaper. It would also ensure that everyone gets an access to better technology-e commerce, computer browsing- whatever content a person prefers to consume. Data aka information will be easily dessiminated and I think if it will be combined with the blockchain, it will create almost an airtight security. I am saying almost because somewhere, there might be a thing or two that needed fixing.
In regards to computer getting smarter than us, machines operate basically through logic. It does not know non tangible things like emotions or thoughts. In the end, they're just machines. Humans are creative and innovative. Machines cannot perform more than what they had been designed to do.
