The ‘future’ is not inevitable. There have been countless collapses in history. Our technology doesn’t make us immune. The people of the major Bronze Age powers probably thought the same.
Also we do not have the means for weather engineering. If you’re talking about SRM, we have no idea what its consequences will be or how to do it effectively. It’s all theoretical. No aircraft we currently have can do this stuff. Sure, we could design it and build one, but then you need global governance to actually implement it properly. Not to mention the risk of ‘termination shock’ and countless others.
