Ask HN: AI Replacing Engineers – Firsthand Stories?

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?
