>Congratulations on building your time machine. And welcome to 2020. Please don't do that. You are using sarcasm to ridicule the guy you are responding to, and that's an unproductive way to argue. It is also against HN comment guidelines (https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html): "Be kind. Don't be snarky. Comments should get more thoughtful and substantive, not less, as a topic gets more divisive. Have curious conversation; don't cross-examine. ... Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
