It's been slow, metaverse happening.  We got the world wide web
   instead.  Now we have social networks.
   The movie The Matrix tacitly hid that whoever designs a fake reality
   controls its laws and hence its people's choices, which became more
   apparent to the public with social networks.  Changes if
   spies/hackers/ais are directing things instead of the virtual reality
   manufacturer.
   Regardless, having a safe metaverse is analogous to have a safe line of
   brain implants, a safe monopolistic social network, a safe monopolistic
   news agency, a safe GPU provider etc.
   We need things to be run by public, free, community code, and most
   important we turn into borg slaves if we rely on a system, cultural
   component, or technology that is monopolistic, anywhere in the chain.
   It's happening right now with the IP stack.  People look to radio,
   snail mail, personal visits, but really everyone's addicted to the
   internet.  A big wifi antenna labelled "IP routing infrastructure"
   sticking out of everybody's eyeball.  As security reduces, our tools
   prepare to instill our next global dictator, because in the span of a
   decade or two we all forgot how to use a pencil.  Nobody paid attention
   when some raised warnings, because nobody knew all the cards that might
   be played.
   If there's a vulnerability, somebody can use it to prevent the closing
   of it.  Others will be planning for that.
   So, like everyone else will common-sensically parrot, make sure to hack
   and clone your metaverse.  Run it on a toaster you built yourself, or a
   3d-printed intelligent rock.  Reverse engineer the marketing protocols
   and get a collection of vr-addicted human drones to build a real world
   set of open hardware community spaceships.
   Then we can all see the real galaxy of aliens, for free.
