At some point we will be "replaced". When you get AI to be able to navigate all user interfaces, communicate with other agents, plan long term and execute short term, we will no longer be the main drivers of economical growth.

At some point AI will become as powerful as companies.

And then AI will be able to sustain positive feedback loop of creating more powerful company like ecosystems that will create even more powerful ecosystems. This process will be fundamentally limited by available power and the sun can provide a lot of power. Eventually AI will be able to support space economy and then the only limit will be the universe.
