A-Island or AIsland?
Recently I was in Shanghai for work and our hotel was near this impressive building. Taking an after-dinner walk there, I found out it as something related to AI - in fact it is described as the Zhangjiang Artificial Intelligence Island, or in short, AIsland. It was indeed on an island and of course I did immediately think of A Island on Justinian.
As to whether there is an AI on A Island, the answer is almost certainly, yes, to support the work of the Global Council, but probably a worker AI, focussed on one task, the activities of the GC, rather than an aware artificial general intelligence with motivation and agency, such as Humai or Zeus.
