Maybe I am too paranoid from people "just asking questions" all the time but actually pushing something they are too afraid to say out loud, but to me it seemed like exactly that behaviour. If he was actually interested in providing information on that "debate" he could have talked about it with the actual experts in his video but he just leaves it as an open question. To my understanding this openness is a strong misrepresentation of the scientific consensus because this exact motor has been used by creationist for a while and their arguments have been debunked by scientist for years.

Not sure if he used the actual words but he was definitely making the point that it is extremely complex and any less complex version of it could not function. Which is exactly the concept of irreducible complexity

Edit: see @scarabic 's comment for a transcript of that part of the video

Actually, that was the video that really gave me a bad feeling about him after watching his videos for a long time. The way he ends the video saying "there is an active discussion on how something so complex could have developed because of its irreducible complexity" just seem like religious, creationist dog whistling and sowing doubt about evolution. He seems to be implying that such a structure could not have been produced by evolution and that there must be an intelligent designer. The book he recommends is also written by an religious, creationist philosopher.
