From Fast Company:
Microsoft will soon preview a version of Word that will use artificial intelligence to make your writing not just grammatically but politically correct.
Microsoft doesn't call it a "political correctness check," but that's essentially what it is. Not that there's anything wrong with that.
Actually Microsoft calls it "Ideas in Word," which refers to a series of AI-driven features that help you format your document and write better.
For instance, Word will decode acronyms for you, and tell you how long it'll take to read a given document. It'll also underline words or phrases that sound insensitive, and suggest corrections.
Say you write, "We need to get some fresh blood in here." The AI is likely to underline "fresh blood" and suggest "new employees" instead.
