I am hoping this isn’t an implication that C is legacy and C++ is the modern and the future. :-)
struct point { int x; int y; };
int main() { struct point p = { .y = 0, .x = 0 }; }
error: designator order for field ‘point::x’ does not match declaration orderBut Arduinos are programmed in a dialect of C++, so it will become necessary to enable it in the near future, i.e. by 2030. Civilization might fall first.
I would add, more enlightened places.
But competent C++ programmers are expensive. It is harder to tell whether a C programmer is competent, because the code they write has less room to be better than minimally tolerable.
Consider that the number of programmers adopting C++ every day far, far exceeds the number adopting Rust, and the rate is increasing faster, in absolute numbers, than ever before, it is hard to imagine any scenario where C++ is less popular, relative to Rust, than today. Yes, C++ usage will less than double, while Rust usage will multiply, but the absolute difference in number will be much larger than today.
Touch base in 5 years... Rust will still be a niche language due to its complexity. (IMO, Go has a better chance of at least picking up a few percentage points.)
Rust offers the idea of safety and security, but at the same time hedges itself with unsafe - fine, sure. However, my work would be nearly 100% in unsafe. So it results in an unpredictable, complex, unsafe language - a non starter.
