Surviving Internet Hate

The tone shifts here into something more personal. DHH acknowledges that coming into the Linux community as a two-and-a-half-year newcomer draws legitimate pushback from people who've been doing it the hard way for decades. His equanimity about critics — 'every time there's a new flare-up, it's less' — reflects genuine experience with controversy across his career. The three-week X detox this summer came when his feed had somehow tilted toward politics and away from tech, even when he agreed with the political angles being presented. The algorithm holds up a mirror to your revealed preferences, he notes, and those aren't always pretty — Jung's shadow territory. His meta-observation about X actually improving because Bluesky and Mastodon became honeypots for the most aggressively tribal users is counterintuitive but backed by his personal experience.
The Jevons Paradox and AI Employment
When ATMs arrived, bank tellers feared for their jobs. Instead, branch costs fell, banks opened more branches, and teller counts increased. The same Jevons Paradox might apply to programming: as AI dramatically lowers the cost of software, demand for software could explode and create more developer opportunities — though DHH admits this isn't guaranteed.
The Setup: 16 Machines, Herder, NeoVim
DHH runs Claude Code in tmux via a tool called Herder across 4-5 networked machines connected by Tailscale and GL.iNet Comet KVMs. He manages ~16 parallel agent threads, uses NeoVim as a project browser and LazyGit for changelogs, and orchestrates everything on Linux. Each machine runs 3 agents simultaneously.
