Someone using md in their account name for 14 years is really committing to the bit if they aren’t a doctor.
I went back in their comment history before LLMs existed and found comments where they claim to be a doctor and sound like they know what they are taking about. I’m not a doctor but my wife and many of our friends are, so I know what they sound like.
I appreciate your feedback, I did not dig through their comment history to make that discovery, but saw someone showing full trust in a random user on an anonymous forum and wanted to encourage more critical behavior.
