The success of AI doesn't hinge on whether you can vibecode it all or even one particular sector really well. For example, despite several attempts to make vibecoding PCBs, it's still pretty crap. But it's really useful as a copilot, human in the loop for targeted tasks in electronics. Same for CAD work, not so good at drawing but still useful at looking at an image, understanding it, and answering specific questions.

Whether the value attached to these companies is grounded in reality is a different question.
