TL;DW: they assume technology will magically “fix” the climate crisis and no big changes to society or the economy are necessary. thus perpetuating and worsening the climate crisis by pretty much telling people “it’s gonna be fiiiiine”…when it really won’t be “fine”.
edit: note, that most of their content is fine, just the climate “solutions” and stuff are…so optimistic as to be misleading. their physics and futurology stuff is fine. also way oversimplified in many cases, but fine.
