He is my hero because he has won capitalism and entrepreneurship. He is incredibly wealthy for all the stuff that a normal person needs, does what he really enjoys and has no shareholders to worry about.
The only other company I know of that is similar is Valve. Both at the cutting edge, doing very interesting things and just leading a meaningful, stressless life.
I am modeling my companies heavily on Wolfram and Valve. May other companies take some notes from them too.
I didn't put a huge amount of effort into the sound isolation, the acoustic panels mainly reduce echos but do nothing for low vibrations (people walking around the house, cars idling outside, airplanes). I have total control over the lighting (I don't want to see any daylight when I'm working). It can get a little stuffy if I don't turn on the AC/fan.
Personally I love working in a little space with my back to a wall. Because of the acoustic tile, many people think I'm just in a work office. I find the limited view (basically I'm looking at a monitor with a wall right behind it) keeps me from getting distracted.
