Why GNU’s 40‑Year Journey Still Shapes Modern Software

On September 27, GNU fans in the United States and Switzerland will celebrate the 40th anniversary of the GNU project, marking four decades of a still‑young open‑source era.

Origins of GNU

On this day in 1983, the controversial Richard Stallman announced his project to create a new operating system, recursively named “GNU’s Not Unix.”

Celebration Events

The Free Software Foundation will host two special events: a “Hackers’ Day” at its Boston headquarters and a celebration and hacker conference in Biel/Bienne, Switzerland.

GNU’s Successes and Failures

From a narrow, concrete perspective, the GNU project has failed to deliver a complete, usable GNU operating system; the GNU Hurd kernel remains unfinished and not ready for daily use.

The Hurd was an ambitious micro‑kernel design, but few projects have succeeded in making it work well. Modern research has shifted to micro‑kernels like seL4, while Minix 3 provides a more complete example.

Before developing Hurd, GNU almost entirely chose the BSD 4.4‑Lite kernel, as described by Hurd developer Thomas Bushnell, who believed it would achieve great success.

All this occurred before the invention of Linux around 1991.

Nevertheless, GNU has achieved great success by reshaping the computing industry. Numerous GNU‑based operating systems run on the Linux kernel, such as GNU Guix (pronounced “geeks”) and several fully GNU‑coded Linux distributions.

More broadly, Stallman’s promotion of the free‑software concept has fundamentally transformed the software world.

Value to the Industry

Eric Raymond and Bruce Perens coined the term “open source” to market the idea to businesses, leading to countless projects and products hosted on open‑source platforms.

At open‑source conferences, thousands discuss open development, software licensing, and the ability to modify and fork code under protective licenses that embody Stallman’s public‑ownership vision.

Stallman’s Return

Richard Stallman, born in 1953, graduated from Harvard in physics and worked at MIT’s AI Lab (1971‑1984), creating Emacs and early AI technologies.

He has received numerous awards, including the ACM Grace Hopper Award, ACM Software System Award, and a MacArthur Fellowship, and was inducted into the Internet Hall of Fame.

After resigning from the FSF in 2019, he returned quietly in 2021, stating he will not resign again.

Community Expectations for GNU’s 40th

Fans and open‑source enthusiasts expressed gratitude and high expectations, praising Stallman’s contributions to free software, legal frameworks, and the ongoing fight for free options in computing.
