Imagine, if you will, that NASA updated its website to suggest gravity might not exist, prompting CalTech and CERN to release statements saying, "With great sadness, we can no longer recommend listening to NASA."
This is what's happening in epidemiology.

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.
Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

My other other conclusion is that "outfit recycling" should be the highest badge of honor in fashion and so we should STOP complimenting people for new clothes and START complimenting people who wear the same thing again.
