Take what you did in the past year. Write down every product decision taken, every interaction with other teams figuring out APIs you had, all the infra where your code is running and how it was setup and changed, all the design iterations and changes that had to be implemented (especially if you have external partners demanding it).

Yes. All that you'd have to input into the AI, and hope it outputs something decent given all that. And yes, you'll have to feed all that into AI all the time because it has no knowledge or memory of "on Monday the new company bet was announced in the all hands"

You will be fine.
