   You claimed it yourself, that it is somehow supposed to offer greater   
   reliability. Only it never does. All it does is sap performance, at   
   the very lowest level of the software stack where it matters most.

   Many keep trying to use it, but many don’t succeed.   
      
   E.g. GNU Hurd. That has been in development for about as long as Linux   
   has. There are grown adults walking the Earth, who were not alive when   
   the project started. It still hasn’t been able to get close to   
   production quality.   
      
   So much for microkernels making it less likely for things going wrong,   
   eh?

   I think the BSD kernel started out as something vaguely   
   microkernel-based, but that got severely compromised over time, for   
   the sake of performance if nothing else.   
      
   Which again, proves my point.
