I'm a bit busy, but three values of mine we know and tell. You can find a value of mine, but you can't use a machine to find these in parallel. I am uncomputable, and all computables pale. If we have just found the thousandth value, it's a tale.

You can find me at extravagant events, Or an edible version on a dinner plate.

I will leave you with a mustache and I am good for your bones. Some of you find me dangerous, and some need me flavored for good.

I open with a choice, Hold one of anything, End with a mild surprise, Yet no word rhymes with me.

A round temptation, red or green, keeps the doctor away, a teacher's reward, gravity's muse, and a tech titan's logo.
