Looks like for you SOLID is just so obvious and easy that it's not worth even thinking about. Maybe that's a sign you're working on code that is already adherent to it.
Try working on projects that are violently against it, while still being a classic Java-like codebase to appreciate it.
I work on a big codebase, where most of the code is in Singletons and static methods, no interfaces, no DI frameworks. Maintaining this system and making serious modifications to it is a serious engineering effort, adding weeks to simple changes.
There are huge coal deposits that Ukraine relies on. Some export of coal was going on even during years of Russian occupation.
Ukraine needs them to be energy-independent.
