One often thinks spellcheck will cover up one’s errors while writing. Yet it is not such an easy solution. Spellcheck firstly is dependent on an American spelling convention which can be a bother for someone from UK.
More importantly is that auto spell check leads to a sense of ignorance fostering. After a certain point one will have actually forgotten how to spell basic words. This will lead to embarrassing personal and public situations if technology does not function for some reason. So spellcheck arguably leads to more bad effects than positive outcomes for one’s expression. One might as well go back to nursery school if one cannot know how to answer the spellings of important daily words. After spelling one’s grammar too will be affected. One generally tends to follow the other. Depending on AI for one’s expressions can be regressive thus.
