How so? Even in a jurisdiction where corporate officers aren't required to be a natural person, trying to have an AI CEO is like trying to make a cat/dog a CEO. As a practical matter, it is not a legal entity recognized as capable of entering into agreements so no government or other business will accept legal documents, contracts, etc. signed by the AI CEO or signed by a human claiming to act under the AI's (not valid) authority as CEO delegated to them. If I had to guess the latter would likely be considered fraud.

Unless some movement forms to get broad agreement that an AI instance can constitute a legal person (some kind of AI equivalent of corporate personhood, which nobody seems to like), this project is DOA.

This is one of those rejoinders that tries to be clever but really, really isn't. The "intern as fake CEO" is left holding the bag because it's their signature on contracts and other legal documents. The idea of puppet CEOs to fraudulently dodge accountability existed well before LLMs became a thing. Courts see right through that kind of scheme plus the "intern" is likely to turn coat against the mastermind to save their own skin at the first sign of trouble.

If the paperwork says the intern is the CEO, then the intern is the CEO, regardless of how much the intern's agent's github says otherwise.
