A note on this entry: the channel's captured material assigns under-UI-ing to the exploration piece following Dan Shipper's conversation with Guillermo Rauch — founder and CEO of Vercel, creator of Next.js and Socket.io — about what happens to software development in an AI world. Within that piece's scope, the term sits alongside the conversation's themes: how Rauch spots emerging technology waves early, why he no longer calls himself a coder, what the shift to an allocation economy means for engineers, and how startups can outmaneuver incumbents in the AI era. The captured evidence does not include a verbatim defining moment for the term, so this entry describes where it appears rather than paraphrasing a quotation; if you explore the source conversation, treat any precise usage you encounter as the authoritative one.
