Lisp, Legends, and Link Rage
Inventing the Future, One Lisp Machine at a Time
Old computer dreamers are back — and the comments turned into a retro tech food fight
TLDR: Larry Masinter and Frank Halasz say the old Xerox PARC way of building computers still has lessons for today, especially the idea of creating tools people truly live in. Commenters turned that history lesson into a nostalgia-fueled debate over monopoly money, artificial intelligence hype, and whether the old weird machines might deserve a comeback.
This story starts as a warm, brainy trip back to Xerox PARC, the legendary research lab where big ideas like modern screens, networking, and early linked documents were being dreamed up long before the rest of us saw them. Larry Masinter and Frank Halasz look back on a workplace with almost absurd freedom: come in, chase the idea you believe in, and somehow make sure it was good. Their big point is that old tools like Interlisp, a programming environment from that era, weren’t just museum pieces — they were living systems people actually depended on, and the pair still think that hands-on, home-like “residential programming” mindset matters now.
But the real fireworks are in the comments, where nostalgia instantly mutates into a retro computing comment brawl. One reader sent everyone down a rabbit hole into Japan’s Fifth Generation Computer Systems project, basically yelling, “If you like this, go even deeper,” only for another to immediately faceplant into the most modern irony possible: “too many requests.” Nothing says preserving the future like a dead link moment. Others used the article as a launchpad for bigger hot takes: one commenter argued breakthrough tech only happens when giant companies can milk monopoly money into quality experiments, while another pushed back against today’s “LLMs or bust” obsession, dreaming of a comeback for alternative chip designs and symbolic computing. And then came the sweetest flex of all: a reader casually revealed they owned a Xerox Lisp machine, loved it, and joked they made it worse by installing Common Lisp on it. Peak comment-section nerd comedy.
Key Points
- •The article is based on a March 10, 2025 interview with Larry Masinter and Frank Halasz about Xerox PARC, Interlisp, NoteCards, and the Medley/Interlisp revival.
- •Frank Halasz describes PARC’s culture as offering substantial freedom in choosing research directions, while Larry Masinter says that freedom was coupled with annual accountability for results.
- •Masinter distinguishes research from engineering by arguing that research can succeed even when a prototype fails, if the failure produces understanding.
- •Interlisp is described as a living system that supported real users and workflows, not merely a prototype built for demonstration.
- •The article says PARC researchers understood they were operating ahead of the mainstream, using expensive hardware to explore capabilities that would reach ordinary users years later.
