Business analysts all have their own theories and predictions on GenAI. One evergreen is “summarization”, perhaps gleaned from Model Cards. Same for the recent Forrester event in Milan:

The other main reason consumers are using AI, in Italy but especially in Germany, is to summarize something.

My observation is different:

Anecdotally, random people I meet tell me that „writing E-Mails“ is their top AI use-case. When I ask which product or model they use, it‘s always the free version of ChatGPT (so the one with the least assurances). I have concluded for myself that privacy may actually not matter much in daily business practice - and anyone should be conscious that their E-Mail exchange likely gets fed to the consumer version of ChatGPT at some point (mine certainly has been as well).
