I can get behind that number.

I’m sure it’ll vary widely depending on task and topic, but as a rough number it’s a good enough illustration for how brainless it is to use this tech to find information.

Absolutely wild that, in the year of our lord two-thousand and twenty-five, there's a new research article that calls women "females" but calls men "men"
