It's interesting how thought recognition is merging with machines. As mentioned earlier, a monkey's leg movement brain signals control a robot across the planet, http://www.google.com/search?num=100&hl=en&safe=off&q=monkey+legs+%22brain+signals%22+control+robot&btnG=Search and another monkey mentally controls a robotic arm to feed itself. http://www.google.com/search?num=100&hl=en&q=monkey+mentally+controls+a+robotic+arm+to+feed+itself+&btnG=Search Meanwhile, Eric Ramsay, completely conscious but paralyzed and only able to move his eyes Since 1999 is using a new computer/ brain interface to reads his brain signals. As he thinks about vocal sounds, they are translated in real time. The goal is conversation, by making it possible for him to literally think out loud. http://simplyted.blogspot.com/2007/11/as-speech-recognition-software-morphs.htm He may one day be searching Google, surfing the web, texting his friends, making new friends and maybe show up on Facebook. But as electrodes give way to a skull cap, things like wireless searching, texting, messaging, http://www.google.com/search?num=100&hl=en&safe=off&q=%22Twitter+is%22&btnG=Search Twitter, Facebook etc., could become a thumbless, mental exchange. I can hardly wait for the Blue-Toothers' http://www.google.com/search?num=100&hl=en&safe=off&q='BlueToothers'+&btnG=Search to discover this. I mean it's freaky to watch someone striding down a street, or sitting alone at a table having a conversation with the ether. (Chuckle at this short video.) http://www.google.com/search?num=100&hl=en&safe=off&q=%22Finally%2C+I+know+exactly+how+to+deal+with+bluetoothers%22&btnG=Search Simultaneously, some powerful new exoskeletons are about to overflow from military applications to consumer products. http://video.google.com/videosearch?num=100&so=4&hl=en&q=robotic+Exoskeleton+duration%3Ashort&start=0 My favorite is Sarcos exoskeleton. http://www.youtube.com/results?search_query=Sarcos+Exoskeleton&search=Search No need for a joystick or hand controls. You just wear it, and it mirrors your actions. You can pump a couple hundred pounds, run, box, dance and carry heavy loads up stairs. It doubles as an autonomous robot. Soon they'll park in the garage next to the car or maybe take up a corner in the living room waiting for intruders. This technology is primed to make the link between thought and superhuman abilities as extensions of our bodies.

It's a security best practice in a multi-user system, so I'm not sure what your point is. It was in Unix long before it was in Windows, but that doesn't change anything. The flow goes both ways.

That said, Monad does offer many things that make it incredibly unique as a shell. You can try it for yourself, or simply read commentary from people who have. There are a lot of unix geeks (myself included) that really think it is a lot of fun. I have a lot of Monad examples on my blog, should you be interested.
