Why do Grenades Break AI?

In this video, we discuss Game AI, specifically a problem relating to the NPC AI of Valve's 1998 Half-Life. But, to better understand the problem, we delve into some video game AI history where we discuss pathfinding, Pac-Man AI, Doom AI, Finite State Machines (FSMs), NPC behaviors, Emergent behavior, and a lot more! Honestly, this video was definitely a bit more experimental, I'd like to know what elements you guys liked, and also what could be improved on. I would appreciate the honesty and yeah, I hope you learned a thing or two.
