I doubt this. From what I have observed there are very skilled people in the 
underground cracking community, who have extremely good math and programming 
skills. In many aspects I suspect that there are as many very well skilled 
people doing hacking as there are people providing security measures. I am 
not sure that those doing the latter are necessarily as good as the hackers 
though.
