While that was phrased in a provocative manner, there /is/ an important point here: If one has irreconcilable value differences with other humans, the obvious reaction is to fight about them; in this case, by competing to see who can build an SI implementing theirs first.

I very much hope it won't come to that, in particular because that kind of technology race would significantly decrease the chance that the winning design is any kind of FAI.

In principle, some kinds of agents could still coordinate to avoid the costs of that kind of outcome. In practice, our species does not seem to be capable of coordination at that level, and it seems unlikely that this will change pre-SI.
