Apple's Mac faces criticism as AI agents reshape desktop use

Apple Inc. (NASDAQ: AAPL ) spent decades turning the Mac into a tightly controlled, carefully curated machine.

David Heinemeier Hansson, the creator of Ruby on Rails, believes the AI agent era may turn that strength into a weakness.

Speaking on the Lex Fridman podcast this week, the programmer known as DHH said the Mac has become “a hostile place” for developers working with autonomous AI agents, calling a Linux takeover of the desktop “the most probable outcome at this point.” Why Hansson Thinks AI Flips the Operating System War Linux’s cryptic commands and configuration files scared off mainstream users for decades.

Hansson argues those same traits now suit AI agents, which can navigate command-line tools and edit files for users. macOS, by contrast, deliberately restricts what software can touch.

Hansson said the “locked down, curated experience” that once defined Apple’s appeal is becoming its “greatest drawback.” “I wanna own my computer.

Better yet, I wanna mutate my computer,” he said, arguing the agentic age needs a new operating system.

Apple’s walls exist mostly for security, a concern that only grows as software acts on its own.

Apple Disagrees Apple is pushing back in a narrower way.

February’s Xcode 26.3 update brought AI agents deeper into Xcode, Apple’s software for building apps, allowing them to write code, run tests and fix problems with less human involvement.

But that does not fully answer Hansson’s complaint.

His argument is about letting agents manipulate the computer itself, not just write software on it.

On Tuesday, the company pitched its new M5 Ultra Mac Studio as the “ultimate desktop for on-device AI,” touting up to 512GB of unified memory.

The Bigger Question Is Apple’s Moat Hansson’s broader argument is that AI could make it much easier to leave an operating system.

Today, users often stay on Mac or Windows because they depend on software that only works there, or because rebuilding their workflows elsewhere would be too costly.

AI agents could weaken that lock-in by making it cheap to recreate only the features a user actually needs.

Hansson pointed to Microsoft Office, where most people use just a fraction of the software. “What if we all just build our own 5%?” he asked.

If AI can recreate the handful of tools keeping users tied to one operating system, switching becomes much easier, potentially weakening one part of Apple’s ecosystem moat.

What Traders See Right Now There is little evidence of damage today.

Mac revenue jumped 29% year over year to $10.35 billion last quarter, according to Apple’s results, well ahead of Wall Street estimates.

Hansson is also a longtime Apple critic.

At 37signals, where he is CTO, the Mac stopped being the exclusive default in 2024 as the company moved toward Linux for developers, and he has since created his own Linux distribution, Omarchy.

On Polymarket, Nvidia is the 80% favorite to finish 2026 as the world’s largest company by market cap, versus just 12% for Apple.

Apple fares better in a newer market for second place, where traders give it a 46% chance of finishing behind the leader, ahead of Alphabet at 31%.

In a world where AI agents increasingly operate the computer for us, openness may start to look less like a compromise and more like a feature.
