Syntax - Tasty Web Development Treats

Scott, Wes, and CJ ask whether Ruby on Rails is really dead (and whether Rust is just Rails you don't have to read), then dig into Meta's new Muse agent, which is free, comes with its own VM, and is already reading messages nobody asked it to. Plus: upm, a tiny TypeScript npm replacement, Opus 5.5 moonlighting as a motion designer, Tart VMs on Apple Silicon, and a foundry for gloriously bad web fonts.

Scott and Wes ditch Electron and Tauri for GPUI, the GPU accelerated Rust UI framework from the Zed team. They get into its React-like API, styling that feels a lot like Tailwind, GPUI Kit components, the community fork drama, and the tiny desktop apps Scott has built with it.
