The more natural thing for AI-having Ethereals to do would be to purge Julian, or at most stuff him into a metaphorical box and study him if they think there might be something worth studying, but either way it's absurd he'd be in a position to take over the Tower successfully, as you'd expect the Ethereals to know better.

(In spite of no dialogue hinting at such a possibility) In that scenario, why would the Ethereals be impressed enough by a human first effort at 'strong' AI to coopt it? They'd surely have better AI, not to mention their AI would be vetted so 'goes crazy and betrays us' is a supremely unlikely possibility. This actually all gets jankier in key ways if you assume the no-robots-retcon isn't the intention, especially if you try to explain Julian as a product of papa Shen taking advantage of alien robotics technology.
