By new coll languages I mean Go or Rust. Java and C# are still prominent in business sphere. And I can see push of functional languages as well, such as F#, but that is not so big pressure.
What I also see is big fracturing in ecosystems. When I started developing, I used .NET. I could make WinForm application for Windows and WebForm for Web.
Now there is MVC, Razor Pages, Single page apps (where you have to choose from many JavaScript frameworks). For Desktop app you can write WinForms, WPF, but Electron with .Net seems to be also popular now.
It seems no two companies are using same stack anymore. For me it's becoming quite overwhelming.
I started at this company because of my experience with Perl and Oracle. Now everything I do is Python and Postgres. I’m totally ok with that.
Knowing that 9 years ago I learned python as my first language despite at the time, it wasnt taken very seriously outside single use and a beginner language.
Maybe its just me, but I'm seeing the tech world settle down on a few programming languages and standards. Python, Javascript, PHP, (from the other topic RSS, JSON).
This is good for keeping things modular.
