I'm not an accelerationist out to build the ASI at all costs no matter what ASAP, but if I take the long view in combination with the Dark Forest and Fermi's Paradox, it seems like if we don't ultimately follow this path to its end, someone else who did genocides us instead. I don't see why it has to end badly for us, but I get why letting the current crop of power drunk mean girl billionaires crash the collective car into a tree in pursuit of it does.

What makes you think there is a ceiling to intelligence beyond energy (of which there's a lot more to harvest yet if we just pulled our heads out of our fossil fueled asses)?
