Ask HN: AI Replacing Engineers – Firsthand Stories? (ycombinator.com)
I keep reading about many companies moving to a model where they stop recruiting and replace human engineers with AI. Is anyone part of such a company that wants to share some firsthand experience? What changed significantly in your workflow? On top of the "clasic" GitHub Copilot and/or Cursor, any other tools/agents/automated workflows that are used to compensate for additional human effort? Are you 10x more efficient? Is the effort similar as before, but distributed in other areas?

How a Pipe Organ Works (2020) (pipedreams.org)
…the pipe organ is a big box of whistles. Each pipe sits on top of a hollow wind chest that is filled with compressed air provided by a bellows or blower. Each ‘stop’ at the organ console represents a set of pipes (a rank) of a particular tone color, with a different pipe for every note on the keyboard. Pulling the stop activates a slider under that specific set of pipes on the windchest, making them available as a sound-source.
