Computers already run the world, so far we control them. The concern is AI might take control of them. You have to look at the big picture.
1. Every piece of food you eat, animal or plant based was raised, produced or grown from computers controlling the process, from the water systems to the systems that feed the livestock itself. We can not feed the country without the computers. It's been so consolidated by corporations into mega farms.
2. Every single kW of electricity is controlled by computers
3. Every single major and minor flood control device (dams, levees) are controlled by computers
4. Every distribution system in this nation is controlled by computers
5. Every medical center is controlled by computers
6. The entire financial system is controlled by computers
7. Every rail, air and transportation system right down to the traffic light near your community is controlled by computer
8. Every communication system in this country is controlled by computers including your ability to post in BITOG
9. Every aspect of American lives are controlled by computers that we "the people" are currently control and are at the helm.
The above is jsut the tip of the iceberg. In our world, here in the USA our lives are already controlled by human control of computers.
Life as we know it, can no longer exist without them. In fact their processing power so more powerful than the human brain we wouldnt understand how they would be doing it nor be able to "decode" it.
Dont think it is far fetched that AI can take that control away from us. The brightest minds in the technology world already know this better than anyone in BITOG
There is no such thing as pulling the plug on a server when it divests itself of being "central" like maybe a block chain (bit coin) with no central core. (this is beyond my knowledge but trust the brightest minds on the world to be concerned.
Ps. I dont lose sleep over it. It's very interesting to discuss.
