No, this isn’t a cast iron thing. Using stainless pans, you can get nonstick effects that, in my experience, far outperform Teflon anyway. The process is called “spot seasoning.” I have cooked crispy, cheesy rice noodles with eggs with zero sticking.
I love my cast iron pans, but stainless is my daily go-to. Added bonus: use 100% copper wool to clean your stainless pan. The copper-coated wool at most grocery stores is problematic; you might get a few uses out of the coated garbage and then it starts shedding metal bits.
Both have their place. I think both stainless and carbon steel are extremely cheap in the long run compared to nonstick for the simple fact these pans don’t wear out. Both types of pans will last for generations and can take a real beating, even from metal utensils, though carbon steel does not give a damn about scratches whereas stainless can lose some aesthetic appeal (barkeepers friend can help polish it up though)!
Besides the chemical reactivity differences, stainless pans (especially clad pans with aluminum or copper cores) tend to be much faster to react to temperature changes than carbon steel. At the same time can’t hold as much thermal energy due to lower density, so carbon steel is better for searing a large piece of food without cooling down too much (which can start boiling the food instead of searing).
