What an asinine thing for Core77 to say. Good ideas can come from anywhere. Being a college-trained industrial designer doesn’t somehow unlock the ability to think of ideas, it gives you the tools to make those ideas reality more skillfully and a better chance of being in a job position to do so.
I’m a college-trained graphic designer. If I see a cool design that I wish I’d thought of, I don’t care if the designer is also college trained. They designed something, therefore they are a designer. It doesn’t “sting” that people think of cool ideas who didn’t get a degree in the field.
