It's not just medical threads, it's tech too. You (probably, I'm assuming) just don't know the tech as well as you do the medicine, so it doesn't stand out as absurd to you.
Most of my closest friends are docs. A couple of times at a brewery I've had them read some braindead takes from here for laughs. The people here making wild comments on the architecture of o1 or whatever don't get the same reaction from the crowd.
I see people speaking complete falsehoods about things I have material knowledge of here, and either don't have the energy or the latitude to correct them.
And those reactions to (e.g.) o1 speculation are happening in (e.g.) OpenAI, I'm sure, haha.
