I suspect that 'us' coders might overvalue the language or tools we use, and undervalue the progress that might take place in the context of them. Not just when it comes to the next generation(s), but also in our own work.
For example, over the past decade or two I've 'improved' my toolage by learning vim and emacs, figuring out how to get Sourcemaps and live reloading working, and improving my command-line-fu. And yet, as a programmer, I feel all of these improvements pale in comparison to the stuff I learned that would be equally useful in Notepad as it would be in a decked out Sublime Text/VSCode/Emacs.
This becomes evident when I work on one-off scripts in the Chrome developer tools, or editing stuff using vim on a server. I'm reduced to the most basic tooling, and yet I can get stuff done in a fraction of the time that I'd have needed a few years ago.
