You will have better understanding of technologies limitations firstly, rather than blindly dreaming their fantastic promises, if you are yourself working on the technologies. Secondly, the creators / developers of technologies plus their users / consumers of technologies at 99.999% of the time neglect / ignore / overlook / evade from / had no fucking idea of the serious negative impacts / damages / lethal consequences or Long Term Prices of their technologies, and yet 99.99% of them will fucking not hesitate to seek the maximum exploitations and commercialization ASAP. Lots of times, to only find out unbearable prices and consequences / damages, caused by their technologies, and most usually, only after a fucking long time, as well as tremendous extensive damages irreversibly done. Strictly speaking, ALL and inclusive of the the GREEN and environmental remedy technologies, have negative consequences, mostly neglected, ignored, nu-noticed, swept under carpets, turned a blind eye on, and yes - Move On! Leaving the consequences & damages, accumulatively causing the crisis that planet earth is currently deep within.
You can hardly find technologies that uses no material and energy resources from mother earth, and left heat for global warming, pollutions & other damages, behind after and during their applications, studies and production. In general and overall, it is more realistic and accurate to adopt conservative and negative views on technologies, without accrediting some achievements especially in discoveries and knowledge breakthrough. In strictly auditing, don't be surprised that they did more harms than helps in the most complete overall view.
