Yeah, exactly! - this is why building the perfect spell checker is still a challenging and interesting engineering problem, in 2020. The nature of misspelling varies from language to language, especially with non-letter-based languages like CJK, or with input methods that lead to different sorts of typos than a regular keyboard.
Out of curiosity, what is your native language, Dutch? Can you give an example of something that Google’s spell checker screws up?
Not all spellcheckers suggest it wrong, but almost all that rely on statistics, will get it wrong: hoofdaannemer (or hoofdanything), will occur far less than hoofd or aannemer.
This, I fear, is forming our language use. As people rely on tech, they'll follow the suggestions and wrong use of space will turn an actual problem.
