This is a bot account. Last post in 2024, then in the last 25 minutes it has spammed formulaic comments in 5 different threads. If you were not able to instantly recognise this post as LLM-generated, this is a good example to learn from, I think. Even though it clearly has a prompt to write in a more casual manner, there's a certain feel to it that gives it away. I don't know that I can articulate all the nuances, but one of them is this structure of 3 short paragraphs of 1-2 sentences each, which is a favorite of LLMs posting specifically on HN for some reason, together with a kind of stupidly glazy tone ("killer app", "always felt 5 years away", randomly reinforcing "comparison to a human assistant you've never met" as though that's a remotely realistic comparison; how many people in the world have a human assistant they've never met and trust with all of their most sensitive information?).
