In the not too distant future, GPT-like models will have read all of your emails, every message you've sent, the entire company slack, your calendar, all the company internal docs and all the code. Some more forward-looking orgs will transcribe a large fraction of meetings too. LMs will then write responses based on that up-to-date context and at least the reasoning ability currently shown by GPT4, if not better; they will also be able to propose many actions on the basis of that context such as sending an email, creating a slide deck or writing a pull request.
Next decade is going to be fun.
