Usually “nonstick” in the cooking context means “nonstick without any added fat”. So a stainless steel pan is never “nonstick”.

You need fat on 'nonstick' too. This is another common myth.

Sure, your T-Fal pan will "release a fried egg" instantly for the first 20~30 fried eggs, but then they will start sticking as the coating naturally erodes into your food and your body (including the adhesives that make a 'non-stick' surface adhere to metal). A splash of olive oil is all you need, and olive oil it is one of the healthiest foods out there.

Fear of fat has completely killed this country's health. Fat is a necessary part of food. Fat doesn't make you fat, refined sugar does.

Especially sugar in non-desserts. There is nothing wrong with a sweet piece of cake, but food industry is putting sugar everywhere.

And replacing sugar with sweeteners is even worse.

Although, I did hear that linoeic acid in excess may be detrimental for brain development (and may be one of a handful of reasons that neurodivergence appears to be on the rise). And more than just refined sugar, excess calories make you fat, which both LA and RS have a tendency towards making us eat in excess.

while factual (and quite alarming if I'm honest), it is factually a non sequitur for the commonly held definition of "non-stick pan"

next level is cast iron, good luck

cast iron is so slow and its seasoning is so tedious to build and maintain. I can only really see good reason to use if you cook a LOT of steak or similar. I exclusively use SS, but am I wrong? What am I missing from CI?

I like how you've put it here:

> Needless to say it's a bit more involved, but I felt more accomplished when I figured out how to cook with it.

The rituals and sense of accomplishment. Teflon is very convenient, when it fails you buy a new one, RVS takes a bit more expertise and cast iron is even more of an adventure, it gets better over time, last many generations. It is different in that it heats very slowly but also stays hot when you put it on the table. Nice for slow dining and/or foods that don't stay warm for long. If the handle is also iron you can put it in the oven. You get to cook different dishes that go from the stove in the oven.

Seasoning cast iron has been rather easy, and you can get preseasoned pans as well. My method is: scrub a new (unseasoned) pan well with hot water and a brillo pad, being sure to thoroughly get into any grooves. This is to remove the wax coating present on some pans and to clean any potential surface rust. From there I preheat my oven to 450°F/230°C with my pan inside, this helps drive off any remaining moisture. Once its to temp I pull the pan out and give it a thin coating of flaxseed oil before putting it in the oven upside down for 30min. I do this 6 times, flipping the pan each time, but really 3-4 times is enough. And any fat is also good, I simply prefer flax because it has the best polymerization, which is a debatable quality. I’m just excessive and cast iron collection is a bit of a hobby. After the initial seasoning all you need to do is store your pans in a thin layer of oil if you won’t use them for long period, but even that isn’t a real problem for properly seasoned pans. I’ve never had a pan I seasoned rust.

As for what you’re missing: nothing for cooking smaller foods, but it is unmatched for baking and frying. I’ve found it to be a lot more capable in keeping oil temps consistent and giving good crusts to pan pizzas and cornbreads. So if deep dish pizzas, breads, seared/fried meats and veggies, and huevos ahogados sound good I’d definitely recommend having at least one 10-12” pan around.
