[Interest] vs. Flutter

I probably would have gone with Python, and avoid pointers, as many languages to their best to obfuscate them. But your C was not a bad decision. It is lingua franca. :-)

Just remind them that JS was invented in 10 days back in 1992, and standardized by a committee that had no business standardizing it. That said, with everything targeting JS, it's not a bad decision either.

I'm relatively [adjective] about the new C++ versions. On one hand C++ looks strange. The code to map/filter/transform looks nothing like I'd expect (transform): 
std::vector<int> x = {1, 2, 3, 4, 5};
std::vector<int> y;
std::transform(x.begin(), x.end(), std::back_inserter(y), [](int elem){ return elem * elem; });
auto y = std::transform(std::vector<int> {1, 2, 3, 4, 5}, [int elem] { return elem*elem });

But the new initializer syntax is a joy. 

SFINAE, etc. It creates pretty unreadable code. It takes me several minutes to parse a line of modern C++, which violates several software development principles in that it should be easy to understand, optimized for reading, OTHER Developers, DRY, DR's 10 times harder statement. I've learned that to grok C++, you must first realize that you're not writing a program that does something, instead you're telling the compiler how to build the program. "Doing what you want" is just a "side effect".

I don't know how long C++ can exist with that mentality. The compiler should figure out what I mean. Const should be automatically applied where it can based on code paths. It's something I do, it's easy to determine, and having it auto applied would be just fine. Or maybe have a linter tell you/upgrade it to const. 

Qt is attractive because I "code less and create more". I rely on Qt to translate the C++ committee's/stdlib output into something usable by developers, not language nerds. (Reminder there's more languages than C++, I've got to learn Dart now, apparently)

But the new initializer syntax is a joy, at least.

I dream of a say where we can code things and everyone else regardless of platform can run it. I thought this was going to be .Net CLR, or Java VM, but corporate ownership initiatives derailed them (Much like the "You will" ATT ads of the 90s - we got it, but not from ATT). But C/C++ runs all more platforms/processors. Linux has come a long way in terms of bringing all CPUs a usable software ecosystem. And this though rather obtuse is one reason to pick Qt - that it'll support any system that can run a C++ compiler. You don't technically need to use QML, you can keep going with C++.
