David Heinemeier Hansson, creator of Ruby on Rails and co-owner of 37signals, joins Robby Russell the same week 37signals shipped Basecamp 5 to talk through the shift reshaping how software actually gets built today: why he reversed his "write every character by hand" stance, why he now considers taking AI seriously a professional obligation, and how cheap experimentation ("git reset and try again") is changing 37signals from the inside: designers and PMs working directly in code, and even the rigid six-week Shape Up cycle up for reconsideration.
They also trace the history of Rails, including a backend so stable that a model file written today looks at home next to one from 2013, and take a peek at what's headed for Rails, from a Lexical-based editor ("Lexi") headed for ActionText to native passkeys and magic links.
