Does C++ have a future?

Of course it has many embedded application still use C++ . Still if you are having fear you can learn Rust as it's syntax similar to C++ also it will be in high demand in upcoming years

I doubt c++ and java will stop getting used anytime soon, though time will tell.

No

Maybe in 2-3 years c++ will be like what programming in assembly feels like today. Considering there will be LLMs helping in coding, people won’t be declaring variables anymore. just pseudo code.

It's dead end
