Can someone explain to me why Nvidia stock is going crazy and why Q2 guidance has jumped so much?

I must admit I'm out of the loop on this one. I mostly follow indices, currencies and commodities rather than single stocks.

So I must ask:

Why is the Nvidia stock going nuts? Can someone ELI5 it to me?

Why did guidance for Q2 make such a big jump?

How are they actually benefitting from the birth of AI?
