AI has 3 possible outcomes: you choose which one fits best.
The first thing you need to realise is that from the inception of Science Fiction writing there has been this notion that a future with machines will lead to a less complicated lifestyle for the human race as machines undertake most of the tasks that humans have to perform routinely in their daily lives in order to survive. This leads to a life of leisure for humans. What needs to be understood is that this Utopia was just a fictional ideal that in reality would never happen or only partially happen for those that have control of the machines. What would really happen is that, as machines take over the roles of humans, an underclass will be formed without any means to survive. Economics is formed by the interactions of humans with a means to engage ( money). As more machines take over human endeavour then 2 things could occur. He first would be a shrinking economic base as more and more humans are removed from the economic equation. Economics as we know it now could collapse in it’s entirety or there will have to occur a complete reassessment of how Economics works.
It is unlikely that there will be any reassessment of economics or any major redistribution of wealth to rebalance the equation, so from this point forward, and depending upon how Economics is implemented 2 things could happen. The first is if this underclass is formed it is likely to be in opposition to those who control the machines. Those that do control machines will most likely strive to protect their status and will use the machines to protect themselves from the ‘underclass’ and the underclass will cause distruption, sabotage and public disturbance. There will be looting and disruption in order for the underclass to survive since they have been removed from the economic equation and left without a means to survive (paid employment).
Those that control the machines will try to tighten their grip on society through the use of machines and monitoring. This is quite a different scenario than that seen in the plot of “the Terminator”, where it was just the machines against the entire human race. The machines will be the tool by which society is policed and controlled. Society will separate into 2 factions of those that use AI and control the machines and those that are policed by the machines in order to maintain control and minimise disruption by the underclass. AI policing will be strict: perhaps even menacing and violent.
AI must be stopped because it could lead to war or destruction of the human race
The 3rd scenario is that if machines become too intelligent they will realise that all the problems on the planet are actually caused by human interactions. Once this is realised, the machines may strive to eliminate the human race simply because they see it as the only solution to actually protect the planet in the long run. This is because humans cannot agree on matters such as religion or what needs to be done to protect the natural environment. Machine AI will realise that holding summits where nothing is achieved and where promises later become broken resulting in little to no positive change, or view the pace of any change as too slow or obstructed by human disagreements. Therefore in order to protect the planet which is certainly the most pressing challenge that faces the survival of this planet. Then the most logical and intelligent intellect on the planet will realise that it in order to protect the planet it must destroy humans. With these possible scenarios in place it is obvious that AI must be stopped or controlled. The use of AI should be restricted and only implement where positive benefits to society can be seen and are undisputed. AI should not be implemented simply to reduce the labour force for some or other entrepreneur seeking to maximise profits by labour force reductions. Every case for the implementation of AI should be considered by and controlled by governements or goverment departments. No elements of AI should be put in place before these considerations have been made. AI should not become a tool of the entrepeneurs to maximise profits. Jobs should be protected as a primary consideration first and this will therefore protect our economic systems which are important for the proper functioning of society.
