RailsConf 2023 - The End of Legacy Code by Daniel Huss

Legacy code. Did you just shiver with dread? We know it when we see it, but we don't know how it got there, or why it looks like... this. What if we could change our relationship with legacy code, and shed the weight the name brings with it? What if legacy code disappeared? Throw away everything you've ever learned, embrace the mindset of Eternal Onboarding, and watch as our problems with "Legacy Code" melt away.
