I think you're not considering the effective efficiency difference. This is what scares me about unreviewed (by society, government) advances in technology.

If we increase the efficiency of something (lets say software) by 100%, all the good things that can be done with software gain a 100% efficiency. However, that does not equate to all the bad things that can be done with software gain a 100% efficiency. Many destructive actions are orders of magnitude more efficient than all things constructive (currently), so the net result is that the world gets more dangerous.

For a more physical example, consider that a truck filled with powerful explosives could knock down a sky scraper. That is, for a handful of manhours, it is possible to undo the work of hundreds of thousands of manhours, plus the hundreds of thousands of manhours society would need to divert to managing the after effects of that disaster, and the emotional cost, etc.

There's an underlying efficiency bonus that destructive actions have that is not being accounted for.
