After a cursory read of the PDF, my impression is that the methodology is sound, but the results are blown out of proportion. Of course, if the title was "Boko Haram's internal hearsay about their use of AI", it would draw much less attention.
The weak part is that the interview were with only 15 persons that had knowledge about AI. But, from what I understand, but they never used it themselves. Only the top commanders and the specialized units could send prompts. So it's hard to guess what is the real AI use from a few indirect statements. For example, the commanders could have decided to spread the rumor they were using AI a lot, even if they mostly used plain web search, because they thought it would boost the morale.
For instance, why would anyone pay an AI service to get basic help like that:
> AI provided both immediate technical fixes by teaching “how to uncouple the gun by washing it with diesel” and tactical guidance, in terms of “how to change the military formation so that fighters with jammed guns move to the back and others take their positions until the problem is solved.”
BTW, the paper does explain that Boko Haram was initially just a plain sect, rather living peacefully. Then "following a violent government crackdown and Yusuf’s death in police custody in 2009, the movement turned into a jihadist insurgency". And the last time I read a report by Amnesty International about the conflict, it estimated that 55 % of civilian casualties were caused by the terrorist group, and 45 % by the security forces. The Nigerian army sometimes razed whole villages. Like always, the world is not black and white, good guys and bad guys.
