Spelling is a very interesting thing to focus on. It’s difficult to memorize all of the different rules and exceptions. It takes a lot of effort to do. Yet it doesn’t help you all that much. It doesn’t teach you how to orient the words in interesting or novel ways. It doesn’t make you a better communicator. It makes you an excellent spell check. Like a calculator. Something we’ve had on our computers for decades. You’ve become a worse version of an old tool.
