Congrats, you've discovered people are always joining an anonymous platform, and some want pseudonymity? If I put "md" in my name, am I suddenly a doctor then? Your reading comprehension needs some work, I've been working for 16 years and it isn't being used as a cudgel to appeal to authority, but sharing some context about who I am and what my perspectives are.
The parent comment is demonstrating the exact type of internet savvy critical thinking that you’re ostensibly arguing for, but you seem to be reflexively defensive.
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.
