Has AI been able to figure out conflicting and quickly changing product requirements and implement them on top of existing technical debt? You'll be fine.
People keep saying "ah but it can't do X!". So what? Most of us have multiple decades until we can retire. This AI is getting better every few months. It will be able to do it even faster, better and more cheaply than a human can.
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.
