Heating edible oils to very high heats does tend to produce harmful chemicals as well.

Right, but unlike fluorinated compounds those toxins can be broken down by your body and flushed out (I could be wrong?). For example, alcohol is pretty toxic to us.
Aren't they polymerized into the metal, though? I don't think they come off that easily, barring steel wool or something extremely abrasive.
I don't think chemicals in Teflon come off any easier, but they still do.
Reckons main issue is that it degassed the chemicals into the air. With most range hoods just recirculating the air you're basically getting a face full of it every time you cook.
Isn't it the same issue with oils and high heat during cooking and seasoning?
Doesn't Teflon degrade due to the high Temps? I really don't know that much about it, but it's just the opposite with cast iron seasoning: heat hardens.
We were talking about scrubbing. For heating, lots of carcinogenic compounds are released during the process of seasoning, and I don't see why the same wouldn't continue to happen at high heats afterwards(happy to be corrected). Hardening and releasing dangerous compounds aren't mutually exclusive.
