Life is a coin which has two sides.. If you find happiness, sadness comes along with it.. Similarly, if there is a development, then a threat is also associated with it.. There are ways to find out the threat.. But we cannot help when those talented people themselves are reasons for the threat!!
Its human who develop things.. Unless and until these development are used for the benefits there are no worries.. But human needs to change himself.. Unless that happens, he himself is a threat to other humans and nature!!
So you say that we need not pity the people/nations which bring home problems by their developed knowledge..like global warming, like nuclear technology hazards.....So you say balanced use of anything is harmless😊
