IAWYC, but disagree on the last sentence: it's not an interesting question because it's a wrong question. Superintelligent AI can't have a "custodian". Geopolitics of non-superintelligent AI that is smarter than a human but won't FOOM is a completely different question, probably best debated by people who speculate about cyberwarfare since it's more their field.
"non-superintelligent AI that is smarter than a human but won't FOOM" ...is most likely a better framing of the issue. I nevertheless think a fooming AI could be owned, so long as we have some channels of control open. That the creation or maintenance of such channels would be difficult doesn't render the idea impossible in theory.
From this article by Zoltan Istvan, in regards to the looming Global AI Arms race, he says:
Now, to some extent I expect many Americans, on reflection, would at least partly agree with the above statement - and that should be concerning.

One equivalent postionally reflected statement from a foreign perspective might read like this:
On a related note, there was an interesting panel recently with Robin Li (CEO of Baidu), Bill Gates, and Elon Musk. They spent a little time discussing AI superintelligence. Robin Li mentioned that his new head of research - Andrew Ng - doesn't believe superintelligence is an immediate threat. In particular Ng said: "Worrying about AI risk now is like worrying about overpopulation on Mars." Li also mentioned that he has been advocating for a large chinese government investment in AI.
