We appear to be building the things that creeped me out 30 years ago.  I remember watching a robot bug inject sedative into a person in the &#x27;84 movie &quot;Runaway&quot; [1] and feeling chills go up and down my spine (I was working on stepping motor controllers at the time and it didn&#x27;t feel so far fetched).  As others have noted here, other&#x27;s might use this for more nefarious purposes.<p>[1] <a href="http:&#x2F;&#x2F;www.imdb.com&#x2F;title&#x2F;tt0088024&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.imdb.com&#x2F;title&#x2F;tt0088024&#x2F;</a>
