I don't like C++ Syntax 2. I like the idea of bringing safety to C++, but I believe that Syntax 2 is an excuse create a new language and reuse the C++ name.

It reminds me of what Google did with AngularJS and Angular. It is dishonest on its face and turns me off toward listening further.

C++ has this issue of every few years looking entirely different. There's no long-lasting thought about how changes or additions to the language will echo into perpetuity.

I do not know the totality of what issues we face when working with C++ (or C) outside of say, bounds safety, optimization issues that cause undefined behavior, and implicit conversion problems, but I do have a feeling that every time I see safety issues in C++ (or C) they can almost always be addressed by using an already existing safe alternative, asking whether or not a supposed "valid" optimization should be considered valid if in combination with another optimization it causes undefined behavior, or creating library functions which assist with converting what would otherwise be implicit type conversions to explicit with error checking.
