Well I’m a hardware guy so yeah probably but the two are very much interrelated. It’s almost impossible to have a UX without a UI, at least with computers and software. I guess you could argue voice assistants don’t have a UI but do have a UX but I’d argue the interface is just auditory and not visual. I mean a brick has UX (weight, texture, grip comfort) but no UI so I do understand the difference. But there is no way in hell a normal person is going to understand the difference between them without some serious study. And being this is about those folks, they are interchangeable.
