This opinion is the exact thinking that has lead to the massive layoffs in the design industry. Their jobs are being destroyed because they think lawsuits and current state of the art will show they are right. These models actually can't produce unique input and if you use them for ideation they do only help you get to already solved problems.

But engineers aren't being fired completely in droves because we have adapted. The human can still break down the problem, tell the LLM to come up with multiple different ways of solving the problem, throw away all of them and asking for more. My most effective use is usually looking and seeing what I would do normally, breaking it down, and then asking for it in chunks that make sense that would touch multiple places, then coding details. It's just a shift in thinking like knowing when to copy and paste when being DRY.

Designers are screwing themselves right now waiting for case law instead of using their talents to make one unique thing not in the training set to boost their productivity and shaming tools that let them do that.

It will be a competitive advantage in the future to short sighted companies that took humans out the loop completely, but any company not using the tech will be horse shoe makers not worried because of all the mechanical issues with horseless carriages
