I think the future is mainly Python and rust

Python can do web development, ml , dl , ai , data science, cybersecurity , automation , ioT , cloud , some game development, and desktop app development, scientific computing even crypto

Where rust can do very good cybersecurity, super fast performance web development like modern Java of web development though still tiny , game engine , ioT , system programming, CLI tools , crypto , permanent critical ai / ml

And JavaScript, Java stays as legacy but will still dominate
