... Doesn't "limited resources" basically just mean here ones ability to consider more than one thought at a time? Surely a species capable of collaborative efforts like space travel can handle the complexity of generalizing to say "no, sorry, none of the human-bulldozer designs are okay actually"?

Criticism is not a scarce quantity to be preserved. It spreads, like a fire. Take literally any social movement, like #metoo or BLM. People don’t suppress smaller stories to “save” criticism for bigger stories. The small stories add up. Right now, the F150 is one of the best selling cars in the US. The average American is no where close to criticizing it. But everyone already makes fun of the cyber truck. We can use that.

“Let’s not criticize this dangerous truck design because we should save our criticism!” is the worst way to get people to criticize dangerous truck design.
