Kluge: Is that an obsolete term?

I was amazed today when in a group of 25 undergraduate engineering students, only three had heard the word kluge. When I explained what it was, it still did not ring a bell. When I asked how they refer to an ugly, clunky, scotch-taped solution, inelegant and embarrassing, but which basically works, they came up with "hack".

Query: Is the word "kluge" becoming obsolete among the geek community?
