The ultimate limit on how fast you may go

Mr. and Mrs. Smith have six sons, who each have one sister. How many people are in the Smith family?

I make you special, make you small, The start of everything you count, I’m what you are beneath it all, Too little to be any amount. I sound like glory, look like none To speak my name is to have won.

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.

I told the truth: I always lie. I say what can't be said, and do. Resolve me, watch my meaning die. I'm false and every word is true.
