The internet is abuzz with accusations that artificial intelligence is using up tons of energy and water. People are even protesting the building of new AI data centers, saying they’ll put a huge strain on local resources. But some AI defenders say that this fear is overblown and that AI isn’t actually that bad for the environment. So who’s right? We talk to science and tech reporters Casey Crownhart and James O’Donnell, and computer scientist Prof. Shaolei Ren.
