Assuming it is real artificial intelligence not "AI ®" it will use Perl 5, because of symbol table manipulation. Also it will want to engage with humans for amusement so machine code is out of the question :-).

I have rewritten node.js code in D2 and it was shorter and clearer :-)

I use it, I am not "almost no one" :)

"are all written entirely in Ruby on Rails" ... then promptly rewritten in something else :) https://medium.com/airbnb-engineering/rearchitecting-airbnbs...

Dlang is a statically typed language that is more productive than most dynamic languages

that is _not_ how you judge a _scripting_ language

it is trivial* to add C code to Perl, even when using XS, I guess it is as easy to do the same for Python

if you do heavy computations in pure Perl5 or pure Python you're doing it wrong by definition

*assuming you can write C

"modern" language teaching killed Latin

before that they were teaching it without any stress on grammar, mostly memorizing phrases and short sentences and learning how to use it

... why do you think Perl 5 stagnated for 20 years ?

There were like 10% performance improvements at each new release, a lot of work was done in modules which was by design Perl 5 having a small core and a lot of the features being implemented in modules ...

What feature exists in other languages (except for CPU types: int, float, char etc.) and does not exist in Perl 5 ?

Much as I like Perl I'm not sure I'd agree with you. What does Perl have that Ruby doesn't?
