Ask HN: Would you capitalize on P = NP

The submission yesterday (https://news.ycombinator.com/item?id=27886900) about a proof that P = NP being published (and immediately retracted) got me thinking about the immediate havoc it could cause. Assuming a low enough exponent on the polynomial function, everything we assume about modern cryptography goes out the window.

So, what's the first thing you do when you hear the news? How do you take advantage of the situation?
