English isn't my first language, and I'm treating every opportunity to use the language as a way to learn, including extensive discussions with AI at everyday work. Sadly, I'm not noticing any unnatural wording in its replies.
I'm starting to worry about being gradually affected by AI's style through heavy use. It will make me so sad if one day my written piece sent to others is considered to be AI-generated, while it's written with real effort trying to make it sound natural.
