It's a tool that helps 'trace' a raster image into vector shapes and paths
it's useful for creating vector artwork from raster images - sometimes a logo or icon is only available in a poor resolution raster image, and so having an easy way to convert it into vector saves a ton of time.
I used it yesterday to create an SVG file for CNC plotting of a company logo. It would have taken me a few hours to hand-trace it myself
I sometimes get commissioned to make a logo here and there. This would come in very handy.
Oh jeeze, that's been around as a plugin in inkscape since at least 2011, I remember vectorizing an episode poster from Adventure Time using it. But I'd believe it wasn't quite as good as whatever photoshop had. I used the "never learn photoshop" trick to be happy with what I've got, but then I only edit images for fun.
