we as a species have always been able to choose wisely. We may know more today but I don't think we're any wiser than we were 1000 years ago. More importantly, even if we are "wiser" everyone on earth doesn't agree on what is and isn't wise.
If there were no borders, everyone on the planet was ruled by the same law AND we all agreed on the direction humanity should go in then MAYBE some semblance of control could be put on scientific advancement but we are no where near that point right now.
I'm not advocating "a no holds barred use of technology", I'd love a considered and careful approach to scientific research it's just impossible at present and for the foreseeable future. So, sticking our heads in the ground and crossing our fingers not only won't stop it but will guarantee that we aren't prepared for the consequences.
BTW - There are a few ways to quote but this is the one I use.
When you press the "post reply" button and it takes you to the message box you'll see five icons under the "[Color]" menu (the ones with the "#" icon in the middle) the one on the far left side is the quote button. Press that once, copy/paste the quote you want and the press the same button again. That's it. You can test the buttons just by trying them out and pressing the preview post to see the results without actually posting anything.
