I&#x27;ve talked to both the director of DARPA and Charles Bennett (cosmic background explorer of &quot;science it works bitches&quot; xkcd fame), and both love the XKCD&#x27;s referencing their relevant work.  I&#x27;ve also met Randall himself a few times and he&#x27;s incredibly humble and would pass anyone&#x27;s &quot;normal guy&quot; threshold.
