You know what, this infographic can get in the bin. UI design isn't just about creating pretty things, it's as much about solving problems as UX is. Also, to suggest that UI design is an artistic pursuit is completely misunderstanding what ANY design is. It's not art. It's solving a problem and trying to communicate something. Ugh.

Today, these positions largely overlap with competences. This infographic only mixes in the mind of someone who isn't oriented in the "industry". Sorry, I do not buy it.
