Copilot is not a robot. It's not magic. It's more like a very well-read assistant who has read everything you've written, knows your calendar, and can help you put words together faster.
Here's what it can actually do right now: it can read a long email thread and give you a summary in plain language. It can take your rough notes and turn them into a proper paragraph. It can draft a reply to an email based on one sentence you give it. It can tell you what was said in a Teams meeting you missed.
What it can't do: make decisions for you, know things it hasn't been told, or guarantee it's always right. It's a tool. A really good one. But you're still in charge.
The best way to think about it: it's like having a very capable assistant who drafts things for you to review. You still approve everything. But you're not starting from a blank page.
