Isn't using a laptop as a metaphor exactly an example of

Most often reasoning by analogy?

I think one of the points trying to be made was that because we have this uncertainty about how a superintelligence would work, we can't accurately predict anything without more data.

So maybe the next step in AI should be to create an "Aquarium," a self-contained network with no actuators and no way to access the internet, but enough processing power to support a superintelligence. We then observe what that superintelligence does in the aquarium before deciding how to resolve further uncertainties.

There is a difference between argument by analogy and using an example. The relevant difference here is that examples illustrate arguments that are made separately, like how calef spent paragraphs 4 and 5 restating the arguments sans laptop.

If anything, the argument from analogy here is in the comparison between human working memory and computer RAM and a nebulous "size in mindspace," because it is used as an important part of the argument but is not supported separately. But don't fall for the fallacy fallacy - just because something isn't modus ponens doesn't mean it can't be Bayesian evidence.
