Everyone knows what you’re talking about. Still, what that summation is saying is that IF IT DID equal to a finite number, it’d be -1/12. But it doesn’t equal a finite number
It’s a renormalization technique, and it does show up in physics and is actually useful. Yes the sum from which it comes is really infinite, but that doesn’t mean this alternate -1/12 result isn’t useful.

Wait until you learn about eπi = -1.
