Definitely the remote work stuff, it's ridiculous how many people sit at the desk in a stuffy or crowded office while they could do the same work at home or wherever. Less cars (and less company cars needed, so potentially better pay), less commuters, less pollution. This is something that could benefit the environment, overall health and happiness of people and so much more. Just wish companies would get on board already, it's improving but a lot of countries and companies are still far behind.
