Gordon Chang, author of'The Coming Collapse of China,' offers a readout for the new year. Beginning Monday, technology companies in the U.S. will face new restrictions on exporting some of their more state-of-the-art products to China and elsewhere, according to the Commerce Department. These new export rules -- for companies building artificial intelligence software for analyzing satellite imagery -- are targeting emerging technology that could give the U.S. a significant military or intelligence advantage. A special license would be required to sell software outside the U.S. that could scan aerial images automatically to identify objects of interest, such as vehicles or houses. Elon Musk warns against'advanced AI' and its manipulation of social media.
