> I think Rust's biggest threat is that it's repeating the same mistakes C++ did, despite the hindsight. C++ tried to be everything for everyone -- a language elaborate enough to write applications in a style that appears high-level on the page, and yet not give up on the full control required for low-level programming. For a while, it worked.

... and... doesn't it still work ? An awful lot of C++ applications are being written today, and that can be done at a pretty high abstraction level thanks to the type-level facilities of C++.

Few in the embedded space find it appealing, many of those who use C++ do (as it is certainly a cleaned-up C++, and a nice improvement in comparison), but too often not appealing enough to switch now, and some in the application space who don't know or don't remember the C++ lesson do adopt it now (sometimes out of sheer novelty) but will likely abandon it later for similar reasons C++ was largely abandoned in that space.

are we talking about the same embedded? most C shop migrate to C++. most car brands, and a lot of appliances, use Qt for their UI (C++)

C++ is nowhere near as dominant in the application space as it was in the early nineties. "An awful lot" in nominal terms for sure.

> are we talking about the same embedded?

Probably not. C++'s niche is "low-level with capable hardware." Some "embedded" software does actually run on very capable hardware.

You’re rewriting history here, friend.

Hardly anyone was writing embedded C++ in the 90s. Even nowadays I bump elbows with Developers that refuse to make the move from C in embedded.

If we’re talking Desktop apps, well... yeah, Windows was the new hotness, OOP was hot ‘n fresh, and Visual C++ was a BFD. Once more languages came about, people found ones they preferred over C++ (Java was a BFD).

As to your last comment, I’m guessing you haven’t worked in the embedded space with C++ if that is your conclusion

I wasn't talking about embedded in that section, but about applications, and not just desktop.

> Once more languages came about, people found ones they preferred over C++

High-level languages were used a lot before, like VB and other RAD languages. But the belief was that they'd be too slow for many applications, like servers.

That is correct, and yet the lower the hardware capabilities and the higher the required safety, you see more C and less C++.

what do you call "capable" ? C++ is routinely used on atmega328, a 16mhz uc with 2kb of ram.

The lower the capabilities, the less dominant C++ is, however routinely it is used in absolute terms.
