I'll be closely watching how this shakes out in the coming years. As someone who's done UX and PM work, and has been pushing for a more joint role, it's interesting to see the idea gaining some traction.
I agree. I am currently carving out my place (i.e., creating my position as I go) as a "UX designer" in a Product Management–starved company. It's interesting seeing people be surprised to find out that I don't simply "make things pretty" but help them make sense as well. That right there is both a blessing and a curse.
