GenX was basically told that "Teflon is inert, it can't hurt you."

Well fuck me.

Has there been any evidence to point out that PFTE is not inert?

This article seems to be about the production of PFTE, which is well-known to be quite harmful, but the end product is as far as I know not unsafe to use.

Some, yes. https://www.abc.net.au/news/2024-08-02/is-non-stick-cookware-safe/104160814 Heating pans too hot can partially release harmful chemicals. There's not enough study on ingesting the particles from scraping a pan. I quit using them over a decade ago and replaced them with cast iron. It's a different way of cooking but once you learn works really well.

What’s “too hot” in this case?

Edit: the news link actually works and doesn’t assail me with popups. Here’s the salient part:

When these pans are heated above 260 degrees Celsius, their PTFE coating can begin to deteriorate. But the coating does not significantly degrade until temperatures reach 349C, Professor Jones says.

"So, unless your oil starts smoking, you're not getting to that temperature and even then, you need continued exposure to see any effects, which are usually minor in humans. 

"And that’s assuming you weren’t using an extractor fan or other form of ventilation while cooking."

I always use a ventilator fan, so this is apparently not a problem for me beyond the non-stick coating wearing to the point where shit sticks and I have to buy a new one.
