If anyone is wondering why Javascript is called Javascript when it came out a year before Java, it's because it changed its name from GoScript to ride Java's coattails.

And yes, C++, the language that is still what most things are programmed in, is from '85.

Sad that there's no lua (the best script for making games), but at least there's no Objective C, what apple insists everyone program in for ios despite it being from '84 and inferior to C++.

The inclusion of R is interesting. It's not a language you hear much about.

Almost correct, though its actual initial name is "LiveScript".

tl;dr: by Masato Watanabe (渡辺将人), illustrated by Tani Tadano (タニー只野)

Source:

Part 1: Java、C++、Python…プログラミング言語擬人化計画！ [Google Translate]
Part 2: Perl、C、Scala…プログラミング言語擬人化計画2 [Google Translate]

It's a two part variety feature on Tech総研 (Tech Soken), an online publication on career development for engineers and prospective engineering graduates.

Tech Soken is part of the リクナビ (Rikunabi) network, a graduate job listings service.

The article appeared in an ongoing section called エンジニアあるある (translated very roughly as "Being an engineer, have you noticed…") which seems to cover the effects of the profession on one's personal life and career, often with lighthearted commentary and caricature.

In the article, each character has a short bio that adds some flavor to the designs. Perl for instance is the son of college professors (as in primarily developed for academy), while C++ is an industry leading over-achiever jack-of-all-trades.

The illustrator, Tani Tadano, is a staff member or Tech Soken, and does not appear to have any online presence otherwise. The writer, Masato Watanabe, has way too common a name to research.

Just putting this here for future reference.

The most used programming languages are (roughly in order of popularity by employment, 2021) Python, java, javascript, C/C++/C#, PHP, R. The inclusion of R isn't strange, keeping that in mind.

This was 5 years ago.

As far as I know, Tanii Tadano is working as an editor of Tech Soken's website. And technically speaking, the illustrator's name is not credited on these source pages.
I think the true artist is someone else.
