I had lunch with a couple guys in my industry (unrelated to 3d) a few weeks ago.  One of them pointed out that we could probably all run our businesses just fine with the spreadsheets and word processors available twenty years ago because two plus two still equals four and a sentence is still a sentence no matter what features get added to Excel or Word.  The only difference is our documents today are a little prettier.  Same thing with modelers, really.  They all make verts.  They all move verts around.  Those fundamentals will never change.  Silo does those fundamentals well.
