This. I’m able to be more productive for long hours more consistently than before. The occasions where I’m engineering for 8 solid hours are much more frequent now, and I’m certainly more tired. Almost all of my time is now dedicated to problem solving and planning, the LLM executes and I sit there thinking. Not everyone’s brain or project is well suited for this, but for me as a personality combined with the way my product is structured, it’s a total game changer.
