I've observed another meta as well: IDEs/language servers.
I was writing a Wordpress plugin and by default in PHP all function definitions are global, e.g. is_single that WP defines is global. Naturally to avoid conflicts you would use a namespace, but since most of the examples I saw used prefixed function names, I decided to try that as well.
In my opinion, coding just feels much clearer when you prefix all your names, like my_library_my_func. When I see my_library_, I just immediately know that is my code. If you use different prefixes for different modules, you can tell from a glance which modules a piece of code interacts with. In C++, you can tell a random word is a field by the simple fact everyone prefixes them with m_. I've seen people using prefixes for pointers as well.
This is the same concept you have when designing an UI. Everyone agrees a problem with hamburger menus is that you don't know what's inside the burger until you click on it. If you want people to be aware something exists, you need to make it appear on screen, explicitly.
Instead, languages have evolved toward the very opposite. We ran away from self-documentating variable names and prefixes, and toward namespaces, "const" and other keywords, and "OOP" that feels less object-orientated and more press-the-dot-key-to-get-a-list-of-methods orientated. We depend on docstrings that show in the IDE, and then on auto-generated documentation from those docstrings. Typescript is probably the worst case of this, because it gives you a lot of tools to make the dot work the way you want, you'll spend way too much tinkering with the dot instead of just writing code that actually runs.
Thanks to this, when you look at code, you have to wait until your language server figures out what you're looking at for you. If the IDE doesn't work, it's effectively impossible to code anything in many cases. But the variable names are shorter so people think it's cleaner and better, like removing features from an UI to make it cleaner.
