to arbitrarily high energies, you kind of get nonsense. You lose the ability to predict what is actually going to happen, okay? I'm sort of hesitating because there's a technical way of saying this. I'm not sure if it's worth saying, but essentially to make any one prediction requires an infinite number of input parameters in the theory. That's the consequence of non-renormalizability.
