You need to take a historical look at how technology is developed. Technology requires huge investments by a well maintained and organized society. For example, US government invested for 30+ years in computers before they became a mainstream product. What happens when you take away organized human life (like a relatively well functioning government)? You won't get any technological improvement. Technological improvement requires stable societies and climate change will disrupt all societies on earth. It's even completely plausible that organized human life won't be possible if we don't tackle climate change now. So any hope of developing the technology you are talking about rests on huge efforts to solve the climate problem.
