Again, i have no dog in this fight. I did some digging into teflon at some point though and if are making demands of user skill level when using cookware, teflon is pretty good actually. The issue arises when the layer gets damaged, mostly due to user error. Teflon is used all over the chemical industry for the fact that it does not react with anything. If teflon coating is used by chemical plants that operate on these insane levels of purity and what not, i don't see how it all the sudden behaves completely differently inside of a pan, outside of people jamming their fork into it. At the very least i understand why they thought it was this great thing at the time (to be clear i am not a fan). Insofar durability it remains a ''consumable'' at the end of the day, not some intergenerational tool. In general, a lot of these discussions (the PFAS one for example) would benefit from some contextualization, which is that our ability to measure has increased a bazilliontrillion (a meme factor, obviously, because im too lazy to google the actual number but it is beyond insane) fold in the past decades. The fact that things as such can be measured has been rendered meaningless due to this (because we can measure basically anything), and always requires scale for context.
