Certainly, GNU has matured and accomplished wonderful things in last quarter-century. More importantly perhaps, it's produced wonderful progeny. It has spawned hundreds of thousands of free software projects, thousands of free or nearly-free operating systems, and an unbelievably vibrant global free and open source software community. Beyond the software realm, the free culture movement, most free licensing projects, and much of the access to knowledge movement can trace a connection back to GNU. We are living, and building, a new generation of the free software movement.
As computers are becoming more and more ubiquitous, and affect more and more every aspect of our lives, software freedom becomes a strong necessity. I personally have been involved with free software since late 90s. It gives me the operating system for our servers, our programming language, and our toolkit. It also gives me an amazing community to work and share ideas with. It is hard to imagine working in a world without them.
