We hired a new guy at work that's leading a specific platform initiative.
In person he's very articulate, able to communicate abstract thoughts clearly, states clear goals and how he's learning about the business to develop a plan.
But dear lord everything he writes in email and slack reads like it's copy paste from chatgpt. It's unnerving.
Had a similar experience when my talented lead engineer, who usually grunts in monosyllables and writes terse responses to my apparently intellectually frivolous questions, started adding flowery emojis to his email.
