    I’m a bit saddened this thread has so little activity, 55 comments as of posting, here even though there are half a million people watching the spacex stream. Just watching the launch, the amount of technology and people involved is incredible.

    Prompting claude 5.5 has more appeal it seems.

      For all very real SpaceX achievements there's certain Musk fatigue if you haven't noticed. He's done enormous job to sour people on the idea of becoming multiplanetary species.

        I was all for going multi-planet until I realized the second part of the plan was “and fuck the planet we’re on now.” I’m afraid the second part is coming along much faster than the first.

          How is that the second part of the plan?

            Their plan calls for inaction towards issues that are making this planet increasingly worse for humans.

              Elon is the world's biggest stan (who is actually doing things rather than just talking about it) for solar power and electrification of transport, how is that a call for inaction?

                A funny thing I like to do with people like this is point out the fact that Elon has perhaps done more than any person in history to get humans off of fossil fuels. And then when they sputter in disagreement I always like to ask who they'd propose instead. If they have any answer at all they inevitably give the name of a person who just demands that someone else do something (e.g. an activist or media figure), never actually someone who has put their time, effort and money into building a better system.

                  Ok I’ll play, but you’re not going to like the answer: Xi Jinping. Putting aside all the valid criticisms of China under Xi, the scale at which they’ve embraced electric car and solar energy puts anything Tesla has done to shame. We’re talking more solar and wind capacity added in one year than the U.S. has in total. And China has done more to lower the cost of solar panels and batteries than anyone else while dominating global production. None of it would be possible without an intentional national policy.

                    Nice job. Best answer I've heard. I think Musk is still a better candidate for fighting global warming, as China has also done an enormous amount of polluting, burning of coal, etc. But I'm not really sure how it nets out. It could totally be that Xi's the most culpable for polluting the planet, rather than saving the planet.

                      Rough napkin math: current annual PRC solar output lifetime production displaces / prevents 40billion barrels of oil. ~100mbd per day... i.e. basically GLOBAL oil usage. So every year, PRC solar printing enough solar to replace 1 year of oil use over their life time (assume 20% capacity factor / substitution method / equivalent work efficiency). For reference global LNG is 70mbd, global coal 100mbd equivalent. PRC industry scaled at producing 80 billion barrel equivalent of solar (not enough battery scale to absorb right now)... i.e if there's enough demand / ability to adopt PRC can basically produce enough renewable to eventually displace 2/3 global fossil use if demand steady (it's not). If one attributes solar industrial policy to Xi, like this stupid game to play but if were to play it, Xi's renewable industrial policy alone will prevent doubling of global fossil use at current adoption pace. This just solar, excludes other renewables and eventual nuclear export. The net is extremely easy, global energy demand increases as billions develop, and PRC is almost solely responsible for making sure high % of generation is renewable and not fossil, on global scale.

                      TLDR in this hypothetical, it's just Xi on an 100 story podium, no one else is even in the building. Unless we eventually credit someone for portable fusion, i.e. 60% of global oil used in transport that can't be displaced at utility scale energy solutions, and one credits Xi for MIC2025/PRCEV/battery then no one will ever even dethrone Xi.

                        Ehhhh, I'd say he's not in some league of his own. Xi is also industrializing with fossil fuels and China became the planet's largest producer of CO2 under his leadership and he's been outsourcing dirty industries abroad, particularly to Africa. I'd give more credit to people lower-down the totem pole in China, who are leading the charge for clean energy such as Wang Chuanfu, but he's very explicitly following in Elon's footsteps.

                        It's also a little wild to discount pollution already produced in previously unseen amounts while crediting to them hypothetical future reductions. Last year China had it's highest CO2 emission ever, and even with solar it's possible that their CO2 output will increase.

                          He literally sets / signs off on industrial policy, others follow, This not malaria/polio/smallpox where one can attribute credit and proliferation to X team, and Y policy. PRC aggregate renewable spans 100s of sectors and programs etc, only sensible for credit to flow up to the big man. If one wants to split hairs, can also credit Hu who did indigenous innovation and renewable act, but execution and magnitude increase in industrial capacity expansion realized under Xi. Like literally no one else has stamped and enable industrial policy across sectors to displace current/future emission on order of magnitude of PRC renewable. World power demand is going to increase magnitude via simple 50% percent of world developing... MIC2025 essentially single handedly shifting future curve towards renewable from fossil. Teslas will never displace more emissions than whole of PRC renewable/ev etc. Elon simply is not in the running for global scale renewable adoption and emission displacement. No one is.

                          > possible that their CO2 output will increase.

                          Immaterial if CO2 increases, only useful geopolitical metric is historic per capita emission relative to development level and PRC is low for country blasting through capex heavy capital accumulation phase, i.e. PRC setting standard for low relative per capita emission development. Xi 2012-2026 did ~30% global emissions, ~10-15% global historic for ~20% of population. As long as PRC stays under 20% global historic and maintains above 50th percentile development (use whatever proxy indicator, per capital income PPP etc), they are under emitting / developing efficiently relative to energy use. AKA PRC developing more for less unit of emission. The alternative is not developing which frankly stupid argument/position. For reference US/Europe ~45% historic emission for 10% of global pop. On balance PRC currently grossly under emitting vs historic developmental baseline.
