gollark: I don't see why you would want more disease unless:- you value human suffering or some adjacent thing- you think it would reduce total disease over time, which is irrelevant if you just entirely wipe it out with technology™- you value "balance" or something as a goal in itself, which seems bad
gollark: Also vaguely patronising I think, but hard to tell.
