Hopium is a powerful thing. Technology could solve so many of our problems if used right for the greater good of all mankind and not for the benefits of a few selects. Unfortunately and seeing where the world is currently headed, the future is far more likely to be a dystopian technocratic nightmare than a social and ecological paradise.
The #1 problem we are facing is biodiversity collapse and the people in charge don't realize or don't want to realize the sheer scale and danger that this problem poses. Climate scientists have been warning the political elites about climate change and biodiversity collapse since 1972, but their warnings have fallen on deaf ears. The generation in charge at the time chose to ignore those problems thinking that the next generation would find a solution to it, and the next generation did the same.
We are the third generation and we are running out of time, climate change has now become a self sustaining feedback loop as increased temperatures melt the permafrost, that contains methane, that itself increases temperatures even more, that melts even more permafrost, that releases even more methane, etc, etc... the solution now isn't just about pumping less carbon into the atmosphere but about actively capturing methane from the atmosphere, the problem has become much bigger than it was just 15 years ago.
Climate change will lead to an already well undergoing biodiversity collapse that will result in the death of ecosystems and the collapse of the natural environment that sustains us all. Those who believe that humans can exist without plants and animals around them are delusional. And we are nowhere near replacing our bodies with robotic bodies, or transferring our consciousness into computers, or some other transhuman science fiction fantasy, nowhere near it.
