Linux creator Linus Torvalds has never been one to hold back his true feelings, and his latest target is none other than tech titan Elon Musk. In a recent viral clip, Torvalds sharply criticized the idea of measuring a developer’s productivity by the lines of code they write, an approach Musk notably pushed for at X (formerly Twitter). The Linux founder’s blunt assessment? Anyone using that metric is “too stupid to work at a tech company.”
The Unfiltered Voice of Tech
Linus Torvalds, the Finnish-American software engineer who gifted the world the Linux kernel, is famous (and sometimes infamous) for his no-filter approach. He has openly criticized major players like Nvidia, AMD, and Intel. He’s engaged in public spats with conspiracy theorists and even voiced his frustrations about the popular platform GitHub. His directness, while occasionally deemed rude, is a trademark of his influence in the tech community. This time, his crosshairs are fixed on the owner of X, SpaceX, and Tesla.
The Perfect PC Build and the Viral Moment
The controversial comments came during a collaboration with the widely popular YouTube channel, Linus Tech Tips (LTT), run by Linus Sebastian (no relation, despite the shared first name). The hour-long video, which details the process of building the “PERFECT Linux PC,” included a short exchange that has since spread rapidly across the internet.
The conversation that led to the strong statement was subtle but impactful:
- LTT: “There was a recent thing from a major tech company where developers were asked to say how many lines of code they wrote, and if it wasn’t enough, they were terminated. And there was someone here who was extremely upset about that approach to measuring productivity because it means nothing.”
- Linus Torvalds: “Oh yeah, no, you shouldn’t even be upset at that point. That’s just incompetence. Anybody who thinks that’s a valid metric is too stupid to work at a tech company.”
- LTT: “You do know who you just said that about, right?”
- Linus Torvalds: “No.”
- LTT: “Oh. Uh… he was a prominent figure in the improved efficiency of the U.S. Government recently.”
- Linus Torvalds: “Oh, apparently I was spot-on.”
Torvalds’s spontaneous, uninformed judgment turned out to be a direct hit on one of the most powerful people in the industry.
The ‘Hardcore’ Culture and Lines of Code
The LTT host was clearly referencing an incident that occurred shortly after Elon Musk took over Twitter in late 2022. During the initial push for a “hardcore” work culture, Musk made headlines by demanding that all employees print out recent code for review by senior staff. Developers were also instructed to personally email Musk their best pieces of code and a summary of their recent commit history.
For seasoned software developers like Linus Torvalds, this approach—especially the focus on the sheer volume of code lines—is viewed as fundamentally flawed. A good developer knows that productivity and code quality are not measured by how many lines you write; often, the best code is concise and efficient, meaning fewer lines are needed. A metric based on lines of code encourages bloat and poor practices just to hit an arbitrary number, undermining the goal of creating clean, maintainable software. For a figure who created an entire operating system kernel, this basic misstep in developer management is seen as a sign of deep inexperience or, as Torvalds put it, “incompetence.”
Why Torvalds’s Opinion Matters
This public rebuke from the man who gave us Linux carries significant weight. Torvalds is revered for his technical acumen and his commitment to open-source excellence. His comments reflect a widespread sentiment among veteran engineers who view Musk’s management style, particularly in software development, as simplistic and disconnected from the realities of complex coding projects.
While the conversation between the two Linuses was lighthearted, the core message is serious: when you manage highly specialized technical staff, you need to understand their work. Torvalds’s condemnation highlights the critical difference between technical leadership rooted in engineering expertise and business leadership that attempts to apply industrial-era metrics to modern software creation. The fact that the Linux creator Linus Torvalds was “spot-on” without even knowing the target’s identity speaks volumes about the reputation of this particular management tactic. Linus Torvalds has clearly indicated he is not a fan, which, considering Musk’s controversial history in the past few years, is a position shared by many across the tech landscape.
