I like to create a design with one model, sync it to another and iterate on it, then potentially go to another to apply/implement.

Such of a Claudism. Not criticizing, just noticing.

You can do LLM->3D Printed models now. The drone can fly in and pick them up and bring them to the location you want. They can assemble structures. All automated, all LLM driven.

Things are changing. What was true, no longer is.

On my team we were expected to work 90+ hours a week, and were told we were slackers if we were unwilling to work Sunday afternoons. But I've heard from others that some teams are a lot better.
