writes "Gigaom reports tbat while speaking at the Bloomberg Energy Summit on Wednesday, former NYC Mayor Michael Bloomberg said he gives "a lot of money to the Sierra Club" to help close dirty coal plants, but added that as a society we have to "have some compassion to do it gently." Subsidies to help displaced workers are one option, said Bloomberg, while retraining is another option. But, in a slight to the tech industry's sometimes out-of-touch nature with workers outside of Silicon Valley, he said retraining needs to be realistic, "You're not going to teach a coal miner to code", argued Bloomberg. "Mark Zuckerberg says you teach them to code and everything will be great. I don't know how to break it to you ...but no.""
