   Hmmm... what about Plan9, NextStep (MacOS X)?

   There are big problems with C++, Java, C#. But there are Eiffel,   
   Erlang, Smalltalk, Common Lisp, Oz/Mozart and others. Most of the   
   problems are solved for decades, but the industry does ignore those   
   results, mostly (IMHO). Everybody seems to think, the industry as a   
   whole and individual managers are nearly always make decisions based   
   on facts and rational reasoning -- but that's bullshit. Even if   
   managers would be very rational people (and I don't think so), they   
   just can't make really good decisions, because (as we all know here   
   :)), they just don't know all facts. So they decide based on uncertain   
   knowledge and I think at the moment we are sitting on a local extremum   
   (but a very very bad one compared to the global maximum).

   That maybe true, if all you know is something like C++. Just take a   
   look at Smalltalk or Common Lisp -- both available for more than two   
   decades and the knowledge they are based on is much older.

   For this you should take a look on Oz/Mozart and Erlang (just to get   
   an idea what's all possible and doable for quite some time).   
      
   If you know C/C++ and get a look on something C#, it may look as an   
   advancement. But if you know Smalltalk, Common Lisp or some other   
   languages, even the most hyped features of Python, C# or Ruby seems   
   like going back in time.
