Yuval Noah Harari beat Elon Musk to this in "Sapiens" only to follow up with "Homo Deus- a brief history of tomorrow". But Harari also has the sting in the tail as he states
“The entire contract can be summarised in a single phrase: humans agree to give up meaning in exchange for power.” That power, he suggests, may in the near term give us godlike attributes: the ability to extend lifespans and even cheat death, the agency to create new life forms, to become intelligent designers of our own Galapagos, the means to end war and famine and plague. There will be a price to pay for this power, however."
Harari envisages that “Dataism”, a universal faith in the power of algorithms, will become sacrosanct. To utopians this will look a lot like the “singularity”: an all-knowing, omnipresent data-processing system, which is really indistinguishable from ideas of God, to which humans will be constantly connected. To dystopians it will look like that too.
Lot's to ponder.
In an age when AI threatens to become widespread, humans would be useless, so there's a need to merge with machines, according to Musk. "Some high bandwidth interface to the brain will be something that helps achieve a symbiosis between human and machine intelligence and maybe solves the control problem and the usefulness problem," Musk explained.
