Dev builds px0, a read-only IDE that boots in 1ms and idles at 16MB vs VS Code's 1.4GB

Developer arpitbhayani released px0, a read-only IDE designed for the era when AI agents write code and humans just verify it.
- Motivation: VS Code eats 1.4GB RAM and takes 7s to start; the author argues IDEs should become read-only but instant
- Performance: single static Go binary, <1ms cold start, 16MB resident memory, fuzzy-finds across the Linux kernel's 95,710 files in 6ms, zero runtime deps (no Electron/Node)
- Features: symbol-level navigation, full LSP intelligence, deep search, 280 languages tokenized by Chroma, 14 themes, browser as verification console
- MIT licensed, installable with one curl command
