Thanks, I love these answers! I'll drop a DM on matrix for further questions.

This rather economic recycling allows a living cell to absorb damage that would be catastrophic when you just assume that everything works forever just as you imagined. I don’t have a guess how much more energy would be expended in reassembly of diamondoids, @titotal@awful.systems might have an estimate, but i guess it’s some 1-2 orders of magnitude more

The DMS researchers were estimating something on the order of 5 eV for mechanically dropping a single pair of Carbon atoms onto the surface of diamond. I'm not sure how to directly compare this to the biological case.

Current physicist here: yeah, most physicists are in the "shut up and calculate" camp, and view the interpretations as fun lunchroom conversation.

I also think that collapse is unsatisfying, and I think yud did an adequate job in relaying the reasons why a lot of physicists are unhappy with it. The problem is that "collapse is unsatisfying" is not sufficient evidence to declare that MWI is true and that MWI nonbelievers are fools. The obvious point being that there a shitload of other interpretations which neither feature many-worlds or "real" collapse. The other point is that MWI is an incomplete theory, as there are no explanation for the Born probabilities. Also, we know we don't have the full picture of quantum physics anyway (as it's incompatible with general relativity), so it's possible that if we figure out a unified theory the problems with interpretations will go away.
