I'm hesitant to bring this up since you seem much more informed about this topic, but your statement "Thuen admitted copying at least some components from 'Sophia'" seems to contradict Thuen's statement from the TechCrunch article:
"Visdom is not a translation of Sophia from C to the languages in which Visdom is written. We did not have the Sophia code when we created Visdom."
"Visdom is not a translation of Sophia from C to the languages in which Visdom is written. We did not have the Sophia code when we created Visdom."
So I'm interested in what you mean by "copy".
