You get to enjoy spicy food twice.

Nope, pretty much just the mouth, over here, no butt or tummy brrr-ing.

Well, not all of you. We'll massacre and purge your more moderate siblings and cousins, but we really like YOU, so we're gonna clone you as much as we can.

You're welcome.

Some people just like the pain. I don’t mind it spicy, but the flavor is more important to me.

meanwhile chinese cooking: i'll have all 3 at once please

That's because evolution is a results-driven process. All that matters is making viable offspring. Doesn't matter how it gets done.

Adding to the other responses, birds have simple digestion systems and the seed makes it into the poop, which birds do in flight so the seed will spread. Mammals digestive systems would destroy the seeds before they can spread

Birds eat them without feeling the heat. And they can spread seeds more effectively as you can imagine.

Found the answer myself. Protects against fungal attacks. Also birds don't have the same receptors to capsaicin.

I’m actually surprised that I’ve never found cotton candy coated with tajin, now that you mention it.

Oh, we’re not resistant, we’re just crazy enough to like the pain. Birds are resistant and don’t feel it at all, they can eat chilis like fruits.

There's a book called The Botany of Desire, by Michael Pollan, which is about this. Looking from the plants eye view of things, they have manipulated us into growing them in a huge variety of environments. The book focuses on tulips, cannabis, apples, and potatoes, iirc. Fascinating book.

Two quick examples from the book:

Pot gets us high, now we grow it in closets, warehouses, yards, basements, attics, etc.

Apples don't reproduce true from seed, so Johnny Appleseed brought readily available cider to the Americas. (You need a cutting of an apple tree to grow that type of apple.)

Humans: I will now cultivate you, export you, protect you and make sure you're growing well so I can keep smoking you despite a 50% chance of dying from it.

Tobacco clearly has the last laugh in this story.

Sriracha is now completely random from bottle to bottle. It goes from Tabasco to Carolina Reaper with no visual indicator. Turns out fucking over your loyal farmers and having to constantly scrounge has negative consequences…

Is Tabasco delicious? I find the Sriracha from couple of years ago delicious (the current one is much worse), but Tabasco always tasted like a white vinegar mixed with capsaicin.
