It’s certainly true that much of this stuff has been around a while to those familiar, and I didn’t attempt to frame this article as anything beyond a survey in my original statement. The title is what it is. I’m most interested in hearing perspectives from people who are actually using these methods to do real work, and to hear where the cutting edge actually is these days.

That said, a review like this is still significant to people who are starting out in this field or otherwise not previously familiar, and this is the most recent distillation I’ve seen that is written at a level accessible to a broader science and engineering audience.
