Yes, it's like when people were saying blacksmiths would continue to exist. They do albeit at very reduced numbers. In their place we have mechanics. It will be the same in other industries.
mechanics, welders, CNC operators, CAD operators, industrial designers, materials engineers, metallurgists... really it was an explosion of roles once the technology was there.
This is the positive take I hope to see with AI. Because yes, blacksmiths no longer exist, but all the professions you named above have their roots in smithing.
