In my experience this is untrue... I've worked with C++ on and off (albeit, sometimes reluctantly, so maybe I'm projecting some misery) and a lot of errors in C++ can not be caught until it starts pasting the templates. Sometimes it also fails when linking. Sure, you can always go through the whole build/compile process, but for serious C++ projects that's impractical (even with stuff like (s)ccache) because of how long it takes. And I'm a code quality tooling/intellisense freak to the point it can be annoying for others, and I've never seen a truckload of tooling come even close to simply running "cargo check"

I've only experienced waiting ~10 minutes at most (on decent dev machine) and it frustrated me to no end, but even more serious projects sometimes take hours. Maybe concepts help with this?

And the "jUsT dOnT uSe HaLf tHe LaNgUaGe" argument holds as much as a leaky bucket, because it's hard to agree on what the good parts are in a large team, unless its strictly enforced and audited somehow

I tried rust on and off, since I do not need it for work I never had time to fully dive into it. The news about rust on the web just seems too good to be true, are there any "cons" against modern c++?

yes the cargo and tools etc are great, but I can set up a full c++ build env quickly too, not as good but enough for daily coding.

A big con is that the ecosystem is young still. You can generally find stuff for almost anything at this point (even enterprisey stuff like OData client generators), but they're not "established" the same way their C++ equivalents would be.

GUI and Game dev spaces in Rust are very inovativne and in how they solve some problems, and I'm fairly enthusiastic about both spaces, but I'd be reluctant to recommend them for production, because they're still immature/developing compared to anything in C++

Unless you change header files deeply engrained into your code base (or your entire code is templates), incremental builds should not reach 10 minutes, not to mention hours...

That is what happens when those templates aren't written with features introduced since C++17.
