NGL, writing pure functions in Rust is fantastic. Writing responsible code that handles all the error conditions turns the “happy path” into hamburger. Even with the ergonomics of Result, Option, and even ?, code just sprawls and becomes a readability tradeoff. I’m only a few months into Rust at this point, and I have a lot to learn, but it’s tempting to just .unwrap() and .expect() where I think it’s unlikely to fail.





TL;DR: viable last-ditch option would resemble Highlander 2 in terms of putting one corporation in charge of “protecting” the planet.
Okay, so I was keeping the idea of using deliberate “global dimming” in my back-pocket just so it wouldn’t worm it’s way through the zeitgeist. It’s a viable last-ditch option, but it comes with steep drawbacks. But since we’re here now, fuck it.
We already know that, thanks to requiring shipping vessels to use low-sulfur fuel, cloud seeding can actually reduce solar gain. The problem is that it also blocks out a lot of the light needed for photosynthesis. So this approach punches down on the environment in a completely different way. As for people, while global warming will absolutely impact agriculture, so would less sunlight.

So we could just use airplanes and cloud-seeding. Or we could increase particulates in the atmosphere. Or, as Elon suggests, fly satellites to do the job. The tradeoffs here are awful: disrupt where rain happens, raise lung cancer risks globally, or catapult one man into multi-trilliionaire status while they charge every government on earth for the privilege. Plus, each of those options are more or less forever if we never get around to carbon sequestration that actually works.
We should seriously considering doing anything else first.
Edit: I know I didn’t invent this idea. Rather, I just didn’t want to add to any consensus around it.
