From TFA, “the quality gain is clear to see”, and then they show a picture where pixels have been upsized into weird painterly blotches, with essentially the same level of detail as the original.

This doesn’t seem to produce results which are obviously better than the state of the art from 20 years ago. (Or if so, this article certainly doesn’t demonstrate it.) So is the novelty supposed to be that it’s less computationally expensive?

Here’s a site I just found in a quick web search with some comparisons of other upscaling tools: http://www.americaswonderlands.com/digital_photo_interpolati...
