Lol. I love HN -- the reaction is because this is either straight-faced or tongue-in-cheek, if it's straight-faced, this is stylistically a parody of the infamous "well Dropbox is rsync, it's moat is basically a SWE-weekend" comment
Someone can release this as a product though, exactly like Dropbox. Dropbox basically was rsync, it just had a better UX. There are a lot of people these days that are pretty good at taking ML models and slapping a nice UX on top of them.
Why not? Record a bunch of humans writing, train model, release. That's orders of magnitude simpler than to come up with the right text to begin with.
