I hold much the same opinion as you, but instead of being depressed about it I just shrug and say fuck it. I do what little part I can still, but generally I'm just kind of eating popcorn as the world goes crazy. I just moved out to the sticks to a big chunk of land and plan to hold out here for as long as possible. Already getting ready to get our own garden going this year etc.. Stick a fork in us, we're done IMO. I doubt we'll all die as I suspect the loss will be self limiting.. that is once enough people shuffle off things will balance out and recover to some extent. Of course we can't predict when and what tech will pop up in the next decade or two, especially that the threat becomes more and more obvious with each passing year. Expect to see some Hail Mary projects like dumping iron into the ocean, solar shades/solar blocking etc... We're going to do what we've always done - Ignore the problem until we can't then hope we can engineer our way out of it. This very much reminds me of a car racing a train to the crossing. We'll either get creamed or we'll pull it off by the skin of our teeth.
