I can't tell you who I hate most, Musk or Gates, but I *can* tell you that a 100% accurate rule to see who cares *the least* about climate change is their bank account and these 2 "gentleman"* are at the top of the list (*I use the term gentleman as a substitute of much stronger language that the site absolutely wouldn't let you see)
To them climate change is just a negotiation position to generate *more* wealth I.e. Musk could literally almost end emissions by making all of the patents and tech he holds 100% available for anyone to use and intentionally crashing all of his fortune (Which is mostly speculative based on the *potential* Tesla has to be profitable, not any *actual* profit or products delivered since those are painfully slow and super expensive and sometimes not even at all feasible in reality like the hyperloop)
If you think Gates is any better with his "Philanthropy" think again: We almost had one of the first and consistently effective covid vaccines be 100% freely available to everyone and could have ended the pandemic significantly faster and arguably even prevented the later variants from even existing since a quick and massive worldwide vaccination program would have meant there wasn't enough of a chance for the virus to keep mutating. Bill Gates directly intervened to convince the scientists that were going to just give away the vaccine for free to NOT do that at all, patent it and so and as we're seeing today, is responsible for MILLIONS OF DEATHS by enforcing his 'Philanthropy' which really only serves to glorify himself and the incomprehensible wealthy like him as humanitarian god figures bestowing billions to help the world but not in any way that can actually solve issues but in a way that makes sure that any help is always conditioned to the whims and desires of the ruling class, above all of them the assurance that they remain the rulers and that you know and admire him personally as such.
And yes I think both of them are sincere: they're so far removed from reality that they honestly believe they're living gods and incapable of error and that their actions are the only way forward when in reality they're vampiric leeches that built their power on the backs of the rest of the world and are happy to literally let the entire world die before they consider advocating for something that might actually give us a fighting chance: Complete and immediate revocation of Capitalism and the profit motive to stop emissions dead on it's track no matter how many untold billions the rich lose in the proceeds.
