DHH on Programming, Rails, AI and Productivity
DHH shares his unconventional path to programming, defends the simplicity of 90s web development, explains Rails 8's 'no build' philosophy, and argues against treating open source as a crisis requiring more funding.
Key Insights
The Late Bloomer's Advantage
DHH failed to learn programming three times before succeeding at age 20. At six, he couldn't grasp variables. At twelve, he gave up on EasyAMOS thinking he wasn't smart enough. PHP finally made it click because it gave immediate positive feedback—you FTP a file, reload, and it works. The lesson: early failure doesn't predict final capability.
Chasing the 90s High
The pinnacle of developer ergonomics was late-90s PHP: write a script, FTP it to a server, instantly deployed. No web servers to configure, no build steps. Rails 8's "no build" philosophy attempts to recapture this simplicity. Modern JavaScript should work the same way—browsers now support ES6 natively, making transpilation unnecessary.
The JavaScript Dark Ages
From 2010 to 2020, JavaScript tooling became an asylum of complexity. Projects would break after five minutes of inactivity. The community rewrote frameworks constantly, dismissing anything three months old as "outdated." This was a necessary bridge to get browsers where they are today, but the destination shouldn't be confused with the journey.
Software Writer, Not Engineer
DHH rejects the "software engineer" identity. He's a software writer—crafting code for human consumption and personal delight. The software engineering label flattens the field. A better taxonomy: software writers (high-level, domain-focused) and software mathematicians (low-level, algorithmic). Object-oriented thinking remains his preferred paradigm.
The Three Languages Worth Learning
For web developers: Ruby (wonderful for beginners, no ceremony), JavaScript (unavoidable for the web), and Go (excellent for low-level HTTP work). Ruby teaches fundamentals without boilerplate. Go handles proxies and performance-critical infrastructure. Don't write business logic in Go—that's Ruby's domain.
Open Source as Gift Exchange
Open source isn't a business. Users aren't customers. Contributors aren't owed anything. The model works when developers build what they need and share it freely. Demands for features or funding corrupt this exchange. The MIT license represents the ideal: no obligations, no warranties, complete freedom.
The WordPress Cautionary Tale
Matt Mullenweg's battle with WP Engine violated core open source principles. You can't release software under an open license, then demand payment when someone profits from it. The license is the contract—GPL, MIT, whatever. Rewriting terms after success destroys the trust that lets open source and commercial software coexist.
Trust Your Gut
DHH and Jason Fried are writing a book about trusting instincts over analytics. The gut is a supercomputer processing decades of experience. Bootstrapped founders can follow these instincts because they don't owe returns to investors. Inspiration is perishable—capture it before detailed planning kills the momentum.
