You've heard the predictions from some of the brightest minds about AI’s influence. Tesla and SpaceX chief Elon Musk worries that AI is far more dangerous than nuclear weapons. The late scientist Stephen Hawking warned AI could serve as the “worst event in the history of our civilization” unless humanity is prepared for its possible risks.
But many experts, even those who are aware of such risks, have a more positive attitude, especially in health-care and possibly in education. That is one of the results from a new AI study released Monday by the Pew Research Center.
Pew canvassed the opinions of 979 experts over the summer, a group that included famous technologists, developers, innovators and business and policy leaders. The interviewed experts, some of whom chose to remain anonymous, were asked to join in the discussion of a serious and important question: "By 2030, do you think it is most likely that advancing AI and related technology systems will improve human capacities and control them?"
Nearly two-thirds experts predicted most of us will be mostly better off. But a third thought otherwise, and a majority of the experts expressed at least some concerns over the long-term impact of AI on the "essential elements(要素) of being human." Among those concerns were data abuse, loss of jobs and loss of control brought by autonomous weapons and cybercrime(网络犯罪). Above all, by taking data in and spitting answers out, those "black box" tools make decisions in digital systems. It is an erosion(侵蚀) in our ability to think for ourselves.

The European Parliament has approved a law banning a wide-range of single-use plastic items, such as straws and cotton buds by 2021. “Europe is setting new standards, paving the way(铺路) for the rest of the world,” the European Commission's vice-president Frans Timmermans, who is responsible for sustainable development, said in a statement.
The new plans come after the EC found that plastics make up more than 80% of marine litter, which has disastrous effects on wildlife and habitats. The EU parliament notes that because of its slow rate of breaking down, plastic residue(残余) has been found in marine species as well as fish and shellfish - and therefore also makes its way into the human food chain.
Under the new European law, tobacco companies will be required to cover the costs for the collection of cigarette butts. Manufacturers of fishing tools will also have to pay for the retrieval(找回) of any plastic nets that have been left at sea. There's also a new focus on further raising public awareness, where producers of items such as tobacco filters(滤嘴), plastic cups, and wet wipes will be required to clearly explain to users how to appropriately dispose of them.
The European Commission first suggested the ban in May, which was approved by member states in October. China last year banned the import of 24 varieties of solid waste, including types of plastic and unsorted paper, putting pressure on Europe to deal with its own waste.
The World Economic Forum estimates that there are about 150 million tons of plastic in the world's seas. A study published in Science in 2015 suggested that between 5 and 13 million tons more are flowing into them every year. Research shows there will be more plastic than fish by weight in the world's oceans by 2050, which has encouraged policymakers, individuals and companies into action.
