I think what we might see is a kind of autonomous corporation that is nominally under the control of shareholders, a CEO or a board, but which makes decisions without very much or any human input, and which gains some amount of legal rights through corporate personhood.

It won't be a 'general ai', though. More like a set of loosely connected systems that operate 'in the best interests of the shareholders', however that's defined.

It's pretty much the end state of the trend of pushing decision making to algorithms to remove moral and legal culpability from individuals.
