How has market research and testing of messaging changed given AI?

Once you see messaging that was created with AI, you start to see it everywhere. There are also tools that allow you to scan messaging to determine if it was written with AI (so it can be confirmed). It's placed even more importance on the ability to speak to your audience as a human would speak to them. Words and phrases that don't sound like typical spoken language when you read them out loud are going to feel AI-created and forced. If you want messaging to land, speak it before you write it. That's the best way to prevent yourself from sounding like a robot!
