This refers to the translation of their own material, not the Bible, for which AI will have a different opinion, I suspect, as the NWT is generally considered not good translation.
No one ever accused the Org of not having a big enough translation team or being lazy with translation.
As regards to translation of jw website and magazines, when the source material is garbage, the meticulous translation will be meticulous translation of garbage, not a big deal.
The problem with NWT is not the laziness of the translators, but the dishonesty which led to deliberate changes in the text to fit the JW sectarian dogma. Which, if one believes that the Bible is the word of God, is not just dishonest but Satanic, really.
As for Fred Franz, he is vastly over-respected as a Biblical 'scholar', even among former jws. It is actually funny to even compare him to actual scholars from the 2,000 year old Christian history.
