This had a big thread just a few months ago (https://news.ycombinator.com/item?id=22100736) so this repost is clearly a dupe. Please see https://news.ycombinator.com/newsfaq.html.

There was also a big thread at the time (2018): https://news.ycombinator.com/item?id=18526261. Since the cutoff is about a year, that repost was ok, but the current one was not ok.
