Audience asks how to get from a 5-year-old Rails application with React to the 'dreamy' no-build state Ryan described. Answer: measure client-side performance first with a Core Web Vitals RUM product (e.g. Cloudflare Web Analytics) — backend charts in Datadog/New Relic don't capture user-perceived performance. Once you have data, correlate slowness with commercial metrics (churn, conversion) to get buy-in, then take an iterative approach: rip out the worst or medium-hard wins first, build momentum from visible progress, and tackle the hardest refactors last. Ryan jokes there's no magic prompt.
