It’s difficult to believe that Unix is already hitting age forty! Has it really been that long already? Despite a rocky start in the early years, being able to run this OS on something not even close to a mainframe meant that Unix suddenly becomes a serious player in the budding young IT industry.
Even more interesting, is the fact that the Unix pipelining concept, was the same kind of software usage idea that would later be copied by Windows and DOS years ahead.
Despite it being forty years old, Unix is not likely to disappear anytime really soon. Many businesses are still heavily reliant on Unix. The only thing that might begin driving companies away from it would be server consolidation. And even with this, we are talking a few years anyway.
