Maybe in a century FreeBSD base system will be written entirely in Rust hehe
Nah, in a hundred years there will be >1k additional new languages.
The purpose of each also will be to avoid C, because this didn't actually worked with any former language so far.
And each and every one will be way better than any other language before, above all C, until a new and better language comes out. At least twenty ones will be hyped as the one and only from now on everything has to be programmed in only, while they still not really satisfy convincingly.
At Rust noses were turned up: "What? Rust?! Where you are from?! If you must punish yourself use C++38F462!"
Or there will be some metalanguage, needed to better write in a macrolanguage code which is needed to write unmistakenable texts for telling the LLM to write correct programs....
But then C will still be there - if AI will not really work, like today.
If one day AI works, there will be no programming languages at all anymore.
For what?
Operating systems are not needed anymore, when there are no programs to run anymore. For what you need programs when you have a working AI? To write texts? AI does it. But texts are not needed at all anymore. Who shall and wants to read texts written by AI? AI? Pointless.
Create videos, create music, design machines, design "art", to do any planning... everything is done by AI. So, no extra software needed anymore. For creating presentations? Presented to who? When AI knows it all nobody needs to learn anything. And when nobody needs to learn anything anymore, nobody needs to teach anything anymore.
All you need then is a browser running bare metal as a terminal to connect to AI.
And lots of drugs. What you wanna do with all your life time then, when everything is done by computers? "Enjoy life", sure. How? Like today, feeding the cloud with your smartphone? With what? AI created stuff? For who? AI? Creating music, art, or what, if AI does it?
If humans don't have anything to do of somehow even remote purpose, humans get bored. When humans are bored for to long they become crazy. And crazy humans tend to do insane things.
