This week, Robbie and Adam welcome Kristen Garrett to talk signals, reactivity, and whether we've finally found the abstraction that makes sense. They dig into the differences between signals and hooks, why parameterized signals matter, how async fits into reactivity, and whether Fetchium is about to replace Axios and TanStack Query. Along the way, they debate observables versus promises, the death of prop drilling, quantum computing cracking Bitcoin, why AI needs simpler abstractions, and whether humans are about to become legacy dependencies in their own codebases.
