Agreed. Assuming they took this to its full potential, and created native, cross-platform, desktop widgets for React, what they'd end up with would look startingly similar to QML, except without the easy C++ interop.

I'm a fan of React, but I have no desire to use it outside of the web, and maybe mobile (still on the fence there). For desktop, we have QT, which is truly an awesome native widget toolkit, with many thousands of man-years work in it, excellent cross-platform desktop coverage, along with pretty good accessibility standards.
