I can see no reason to consider those thoughts as somehow not their own when translated from the language they were written in.

Exactly, that's the thing. That although the "original" thought of the author was written in one language, then they used and relied on an "artificial intelligence tool" (the translator) to convert it into another language whose resultant "original" idea may sound a little different if it is not carefully edited and modified.

Same as with ChatGPT and other AIs. Where you elaborate an original question or prompt to the bot so that it generates an appropriate wording on the original subject that you had in mind to develop, in a specific language, and that then it serves as inspiration to create your final blog with the "original" message that you had in mind to communicate. Could you really pinpoint the difference between the results of the "original" content generated between these two types of AIs?

Should be both of this "original content" material disqualified and scrapped of being rewarded. Or just one of them?

The video link is dead. Can you provide another source for the video?

The video is fine here from my end. And you should be able to see it too with no problem. Try to click again but not over the image but on the link to the left of it. And if that doesn't work for you, let me know and I'll try to post the video directly here in a new comment.

Cheers!!
