Similarly to how most web dev isn't exactly on the frontiers of computer science, a lot of day-to-day PCB design isn't about cutting-edge analog or radio stuff. It's just putting the same MCU or SoC on differently-shaped boards over and over again.
If you can reliably automate that, it's still a pretty big deal.
But this is more copy+paste than automating a design process.
Sure, but that's most PCBs (or even subsets of PCBs). Most PCBs are not about using new/proprietary chips with custom requirements. It's mostly connect this MCU with some other ICs, some power delivery, some connectors, reverse voltage protection etc.
