People said that about Cobol. I would expect C++ to be around for another century at least.

Just to be clear, "legacy" doesn't imply "not used." Something can be legacy and very widely used. The question is about growth and new projects.

Even the most ardent Rust supports aren't going to say C++ will disappear.

Name the last green field Cobol development however.

From my own experience with that branch of industry: you won't hear about it because it is likely not open source and those building it don't bother with such things as online communities for project visibility and so on.

But in government and very large businesses (banks, insurance companies, airlines) I would not be surprised at all if there was still greenfield COBOL work done. Just not nearly as much as say in the mid 80's.

That "green field" is pretty sure only done because all the fields next to it are made of COBOL.

If they truly have a green field to develop on, nobody will pick COBOL.

Ah, the 'no true green Scotsman' argument ;)

See also the ton of "No True C++man" arguments in this thread :)

Yes, modern C++ may be pretty good, but how many people actually get to write it instead of sticking with the tried and true ye olde versions actually in the codebase.

Java + C# for sure

Existing projects for sure

New projects from scratch reaching for C++ off the shelf? Probably just video games maybe?
