(This is unrelated to fractals; but you mentioned the waste isolation signage problem: How are we going to convince future generations that a site loaded with the stuff that every dynasty and empire of the 20th and 21st centuries aspired to have, for the immense power it would afford them, is something they should stay away from? Is there a single fantasy/sci-fi series where the ‘poorly understood Superweapon Of The Ancients’ doesn’t get dug up, generally in order to precipitate the total clusterfuck that the plot then has to unravel?)
