@archiloque well, because I had to research this coming from the games angle, I can think of games where programming languages were developed explicitly to achieve the creation of that one game. And the funding from the game sales powered the language.
But in web stuff, there's a chasm between people developing the tools and the people make products and money from them.
@neauoire ahh thanks, I didn’t though about games. For web and business applications were long time maintenance can be an important thing, paying for a thing to be developed new programming language can be seen as risky
