I saw the original tweet before it got lampooned everywhere, looked at the author's bio, and it felt obviously like engagement bait to me. Why would someone actually post about how "humbled" they are that their LLM assistant deleted their emails, and this person is a VP at Meta? I may be wrong but it feels obviously written to go viral. All it would have taken is for the author to not post and nothing would have happened. I was originally tempted to make fun of the author myself but decided not to feed what I thought was obvious engagement bait.
Moral outrage about how everything is in decline is absolutely the viral currency of social media and HN is no exception. I find it amazing how few people doubt the sincerity of the original post. Probably hundreds of thousands of aggregate words spent on how everything is going downhill, but not one on the intentions of the original post.
