What are humanity's problem exactly? Every era of humans had different list of problems. Problems today (climate change, nuclear weapons, etc) are very different than say 1000-1500 years ago. Technology definitely solves lot of problems and some tech enables to scale the solutions (e.g. discovery of antibiotics and tech to mass produce them). But then it gives rise to new set of problems which are much harder to solve. The harder the problems get more collaboration and working together is needed at global scale, which itself is very hard. In this sense, tech can only go so far.
