Any AI assistant, a Mirror, an Echo etc.,
I live above a star, and yet I never burn,
I have eleven neighbors, and yet none of them turn,
I am visited in sequence, first, last or in between,
PRS (& sometimes Q) are my initials,
Now, tell me what I mean.
I hold up the sky; I hold many pounds. Just so you know, I can never fall on the *ground*. I am made of the world; without me you'll die. The ones who survive are the ones that can fly. What am I?
