Yeah, he tries to sell cpp2 as being different to the other alternatives, due to his position at ISO, however it is just the same thing being an alternative language, compiling via C++ translation doesn't change that.
The thing I like about it is that it is the easiest thing to switch to. It provides the path of least resistance for my existing workflows, and that alone is reason enough for cpp2 to win.
That would be Circle, not a language with another syntax.
Circle is nice, but it's not integrated with anything but compiler explorer. Cpp2 has a preliminary CMake integration PoC as of a week after Sutter's talk.
CMake isn't the only build tool in town, I hardly use it for example.
My point was that whatever build system you are using doesn't support circle. The CMake thing was an example to illustrate and contrast.
