But to be fair, this type of buzz-word repetition you also find at business schools without LLM use 😆

But I mean the leading academics in the field are frequently debating the impact of AI (see e.g. www.youtube.com/watch?v=144u...). We can discuss how realistic or smart some arguments are but at least there is a discussion. Never saw anything coming close to this in OR.

Very true, although at least in AI research people are more aware of societal/political consequences of their works. In OR people had some discussions in the 80s and after the neoliberal agenda took over it feels there is no discussion about the inherent OR ideology anymore..

Perfect showcase that for this type of problems using an LLM to search over the space of algorithms instead of smartly searching over the solution space is a complete waste of resources.
