Actually, he's very much the classic style of crank. Instead of giving us a formal proof, his proof is a proof by example consisting of a great deal of code that has to be scrutinized by hand for conceptual errors. It works fine on his test cases of course; so therefore to him his "proof" is "correct."
> How does the solving of problems like these really help the world? I would like a sincere 'down-to-earth' answer that my 89 year old grandfather can understand and therefore be in position to donate to the effort of solving such problems.
Here's one for your grandfather then. When you bank online, you go onto a secure web site. The information you send to your bank is digitally encrypted. A bunch of mathematicians have demonstrated that the 3SAT problem is just as hard, or harder, as breaking the encryption that keeps your grandfather's bank info secure. So, if Romanov turned out to be right somehow, it wouldn't be safe for your granddad to bank using computers anymore, because Romanov would have indirectly created an algorithm that could be used to crack the encryption in a reasonable amount of time.
Other Slashdotters will come up with plenty of other examples why 3SAT is important.
