Yeah I mean sure it’s a slippery slope in that argument, but I’m just not really for killing spider to make funny looking actuators. I belive that the application that they highlight (capturing insect and microelectonics) are a bit of a reach, as in their solution is not super much better. I think kirigami or active entanglement are more useful and less cruel.

For lab mammals I agree but, for now, we do not have a better way. I know people working in pharma and co, and they hate it but don’t really have a better solution. Apparently, organoids are becoming really big as an alternative so it’s nice too see that the science is trying to move away from animal testing. Overall the scientific field usually tries to become less cruel I would hope, and I think that necrobotics is the opposite of that.
