  1. 0:03, I'll translate this: they don't use to spend time building tools. If default Rust has everything they need, ok, go for it. But don't complain later why: - Windows 10 is 40% slower than Linux Mint 19.2, according to my tests. - Loose too much time compiling. - Missed out the chance to has easy-to-use tools, conciliating speed and safety. 2:16, this just means Rust has a better default behavior for safety. As long as I heard, Rust lacks the flexibility of C++. Thus, it ends up been an inferior approach, compared to C++ coded to work exactly how the user wants. 3:41, C++ does it better: it doesn't waste speed tracking object and also deletes it for you, automatically - and allows you to delete it by hand too, if you want . 4:10, this is the problem: converting C to Rust may look as a big win, but missed to opportunity to do it to C++. For instance, that means they won't ever has a switch of "verify my code now" / "now don't verify it" (for compiling speed).

  2. I once took a look on a book about a C++ graphic API by Microsoft. They said it used interfaces all along the code, showing "advantages". And now they want to change it to an incomplete language, that doesn't even has inheritance. So that they are forced to not abuse OO. It seems to me that the company never understood C++ nor OO in depth, able to extract the best out of it. OO was created primarily to secure data. The abstraction was just a bonus, not the main goal. The world missed and misunderstood those concepts.

  3. ​ @kexing_kex  Yeah, and that's a problem. OO is good when properly treated. It was born to secure data. It also has better syntax when working behind the scenes.

  4. ​ @anarchymatt What do you mean by that?!

  5.  @i_forgot1477 Can Rust control how and who can change data?

  6. ​ @Abu_Shawarib I read in a comment from other video, about a guy that work with intensive number calculations. He said C++ was 30% faster than Rust and Fortran, and 50% vs Julia. Since MS uses C++ the wrong way (lots of interfaces, bad for design, 15-17x slower) , I would not wonder if otherwise the difference could be even more. PS: when I made my tests, I made sure Windows wasn't using more than 5% of CPU and HD.
