The history of Artificial Intelligence AI began in antiquity , with myths, stories and rumors of artificial beings endowed with intelligence or consciousness by master craftsmen. The seeds of modern AI were planted by classical philosophers who attempted to describe the process of human thinking as the mechanical manipulation of symbols. This work culminated in the invention of the programmable digital computer in the s, a machine based on the abstract essence of mathematical reasoning. This device and the ideas behind it inspired a handful of scientists to begin seriously discussing the possibility of building an electronic brain. The field of AI research was founded at a workshop held on the campus of Dartmouth College during the summer of Many of them predicted that a machine as intelligent as a human being would exist in no more than a generation and they were given millions of dollars to make this vision come true. Eventually, it became obvious that they had grossly underestimated the difficulty of the project. In , in response to the criticism from James Lighthill and ongoing pressure from congress, the U. Seven years later, a visionary initiative by the Japanese Government inspired governments and industry to provide AI with billions of dollars, but by the late 80s the investors became disillusioned and withdrew funding again.

Over four years in office, the Trump administration has dismantled major climate policies and rolled 11960 many more rules governing clean air, water, wildlife and toxic chemicals.

At the same time, the Interior Department has worked to open up more land for oil and gas leasing by limiting wildlife protections and weakening environmental requirements for projects.

But environmental and legal groups said the rollbacks have not served that mission. Vizcarra, who has tracked environmental rollbacks for Harvard sincesaid the agency under Mr. Trump has often limited its own power to regulate environmental harm, especially when it comes to climate change. Many of the rollbacks are facing legal challenges by states, see more groups and others. Some rollbacks have already been struck down in court. They are summarized at the bottom of this page, and are not counted in our overall tally.

Other reversals that were overturned in the courts were later revised by the administration and remain in effect. Are there rollbacks we missed? Email climateteam nytimes.
