gollark: ¿?????????????
gollark: Why do many of the graphs have two different things for "size" and such now?
gollark: Also, you need to manually collect the drops, though they could be autofiltered easily via introspection modules.
gollark: It could probably work fine, and be a lot faster than digging with pickaxes, if wildly destructive.
gollark: I investigated wide-scale laser mining.
