Drafted a blog post

• Used an LLM to meticulously improve the argument over 4 hours.
• Wow, feeling great, it’s so convincing!
• Fun idea let’s ask it to argue the opposite.
• LLM demolishes the entire argument and convinces me that the opposite is in fact true. - lol

The LLMs may elicit an opinion when asked but are extremely competent in arguing almost any direction. This is actually super useful as a tool for forming your own opinions, just make sure to ask different directions and be careful with the sycophancy.

I have plenty of blog posts sitting in draft for this exact reason. Even though everyone is (rightly) focused on agents in 2026, there is still an art to good prompting.
