I agree it's important to apply the principle of charity, but people have to apply the principle of effort too. If Sharkey's point is about some crucial threshold that continuous systems possess, he should say so. The term "computational" is already taken, so he needs to find another term.

And he can't be excused on the grounds that "it's a short interview", considering that he repeated the same point several times and seemed to find enough space to spell out what (he thinks) his view implies.
