Valentino Stoll and co-host Joe Leo open the Ruby Podcast noting OpenAI is winding down its SOA video app and discuss the broader difficulty of building AI businesses. Guest Bekki Freeman, staff software engineer at Caribou Financial and organizer of Rocky Mountain Ruby, shares conference details (Boulder, Colorado at eTown, September 28–29; CFP opening soon; tickets after the schedule). The conversation focuses on safely scaling AI use in an 8-year Rails monolith: preparing messy codebases with dead code and metaprogramming, strengthening test harnesses and coverage, improving documentation, and being explicit about desired patterns rather than copying existing bad ones. They discuss PR review bottlenecks from increased AI-generated PRs, ideas like specialized AI review agents, stronger RuboCop rules, pairing/mobbing, and remote knowledge-sharing practices, plus security cautions and what AI may and may not replace (tech-debt work vs “taste”).
