That's because no one pays attention to the huge developments in infrastructure or the amazing new technologies coming to market - e fuels like sequestered carbon jet fuel made from excess renewable power, and no it's not a science fiction dream it's happening now. Of course we should have more funding for these things but they are happening.

A huge part of that problem is that people resist even the slightest positive change, paper straws are fine but I bet there are people who like this post who also liked posts complaining about them - if we stopped organized sports and spent that half a trillion on transitioning local infrastructure or establishing carbon sequestration systems with productive use of captured carbon (e.g. building materials that get landfilled at eol) we could move much faster, but no one will give up a single football game to save the planet they'd rather bomb something and feel like a hero
