As I am starting projects ranging from Systems Programming to Cloud and AI, I am looking for a language that is modern, powerful, and has a long lasting future. My number one language is Swift, even if it is currently mostly used inside of Apple's ecosystem, I am looking at creating mostly everything from scratch, and for that I need mastery of language.
While doing research for such, the same two languages that are always advised are C/C++, but only because of how much software is already written in them, which again, is not something that I will even use.
I found on the official swift.org website that "The goal of the Swift project is to create the best available language for uses ranging from systems programming, to mobile and desktop apps, scaling up to cloud services." and "Swift is intended as a replacement for C-based languages (C, C++, and Objective-C).". I've never been happier to read something as such. But are these actually and practically true, or just a language design concept? Would I be able to write software ranging from OS to Cloud Computing, AI, Networking and such?
Thank you for your help and support.
P.S The use of Assembly is not a problem!
