It is not still funny. Something has happened to Adams over the last 6 or 7 years: he started having a lot more sympathy with the Pointy Haired Boss and the CEO, and a lot less sympathy for Alice and Dilbert.

I suspect this is the usual thing that happens to artists when they make it big. They stop being the person that made the popular art. You can point at any number of acts that have suffered this. Maybe money corrupts, maybe having money takes off the pressure that forced the art, or maybe it just makes life easy enough that why bother?
