It would seem unethical to graft a older head to a 16 year old body. In time they would eventually remove the original head. Seems like it would make a good sci-fi film. Seems like it might happen someday because we seem to be genetically producing more of the people that would do such a thing.
Intelligence is the ability to not ignore reality. The stages of getting there can be difficult when our species is still in the early stages of evolution. The first step in getting out of the "survival of the fittest" stage is to realize that discrimination and prejudice is merely a genetic reflex. It is difficult to hate everyone Equally and still have close friends. But still, a small price for intellegence.
There are less fires now than in the past 20 or so years. The size of the fires has increased. The costs of fighting fires and property damage have increased also. I think the percentage of fires accidently started by humans may be less or equal, It should of increased due to population size. I can assume that people are learning not to start them. The size of the fires are blamed on spuce budworm. Spruce budworm is spread by warmer winter weather.. hence gw.
The cleanup cost is estimated at $250 billion. It will only be successful if they throw in a few miracles. They need a way to tunnel under the plant and fill it with concrete before the melted fuel reaches water. They still need a way to store the spent fuel.
They will find that our decisions are random. It can be seen in our political events. We are still in the early stages of evolution...we would not be able to recognize an AI if it was right in front of us.
It may solve some of the problems, But it's unsustainable if you factor in population growth. The only solution is to put them on rails. It will cut the weight of the car in half and double the speed. If the track and the cars are computerized it will be accident free.
