"never reveal the secrets of power to someone who's not intelligent enough to figure them out for themselves"
By that logic, powerful things like The Wheel and Fire may never have spread to cause the kinds of trouble they cause today.
Seriously, though, I don't think we've really done that badly with nuclear technology. Yes, we've made weapons that could wipe out humanity if used on a global scale, but so far, we've also managed to hold off on using them. The argument that they've SAVED lives by being too horrible to use, thus indefinitely delaying WW3 can be made.
I'm not saying that you should necessarily hand over things to the Pentagon (or any other military organization, for that matter), but publishing them should be a no-brainer. People are going to mis-use knowledge, but as a whole, it also helps billions of people.
