If I remember correctly, Malcom did nothing but harp endlessly about how the park was doomed to failure due to various vague non-sequiturs.

All we know is that he predicted fence integrity would fail somehow. We don't know what else he predicted, maybe he just got that one right by chance. We don't know if Hammond changed the park after the paper to invalidate Malcom's reasons for predicting fence integrity failure; if he had done this, Malcom would be wrong despite having predicted fence integrity failure.

We sent people to the fucking Moon _and_ brought them back home. I'll be damned if humans can't solve Jurassic Park.
