This week, I learned:

- WebApps are a depreciated store of value. Earlier, a web-app would have impressed me because the capability to create it is rare, and the effort to create it is high. Today, when I see a "localhost:3000" or a "replit.app" domain, I mentally discount the effort behind it and ask: How rare is the capability to create this with a coding agent and how much effort is it. THAT determines the value of what I see. Part of the value is "Look ma, no hands!" and it's delightful they've learnt. Part of the value is "There's gold in them thar hills!" and use-case discovery is important.
- [WaveCity](https://wavacity.com/) is a WASM build of Audacity, i.e. Audacity running in the browser! [Audiomass](https://audiomass.co/) is a similar but simpler audio editor - again, WASM-based. [Gemini](https://gemini.google.com/share/54d4778ed7bd)
