Ah, I see now!
What you are seeing is most likely companies investing in sales and market placement instead of what we call "Tech Debt". So instead of regularly updating their code base to use the newer versions of the languages or most likely the framework; it becomes basically a rewrite.
So, the CDK is from what I heard here, is .(dot)Net which is a framework. It's innovative and hacker prone, and that disaster waiting to happen. People are laughing at Musk for not knowing how Cobol handles dates, this CDK problem dwarfs that mistake by magnitudes. I think it's criminal as much as a surgeon going to work drunk or high on white powder and then deciding to do brain surgery.
.Net today is a solid framwork (we still pick on it because it's Microsoft) but this is not a bad choice. It's just that you lock yourself into the Micorsoft ecosystem.
As for Ai, Python is the go to that many people tend to use. It's in that same age group as PHP and Java. .Net is a tad younger. Maybe someone mentioned NodeJs to you? Which is about a decade old now but it's relatively new. I'm trying to figure out what language you could be referring to. All the YT videos and possibly the Asteroid game that Musk dropped today would be done in Javascript (nodejs uses javascript) or possibly react. But none of these are specifically Ai tuned languages.
I don't follow the database languages as much because I work with tabular data (think excel worksheets) rather than Ai focuses vector databases. But yes, there are few new ones that are focusing on storing your PDF data into chunks to be used by the Ai. This I don't know enough about.
I'm still trying to wrap my head around the Ai ability.
I originally thought it was like advanced search like what Google did/does. But it's not exactly that. The data training is bit of mystery but the retrieval is actually interesting. It's not a database return answer.
it's like this:
If I say, "Knock Knock ..."
Ai will return 99% of the time, "Who's there".
If I start type, "Hello ..."
You will not answer like Ai because the training data is influenced heavily with data that happens to come from my world, and the answer will be 70% "Hello World".
So, Ai is just a percentage relation to words that come before and after.
It's not Artifical Intelligence though. It's more casnio odds of what word comes next.
I still don't really grasp this.
But coming back to the topic.
I'd need to know the langauges that you heard about to be able to talk about it more.
