It really didn't look good, no. But if what I hear from the devs is any indication, the presentation build was early alpha, and a number of elements in the game were "weighted" to make the presentation go exactly as they wanted it to go as smoothly as possible (AI scaled back, PC made invincible and super-strong, etc.) They've got a few months yet to work out the kinks. But I don't know if I'd expect the AI to get all that great. In general, game AI is rarely consistently spectacular. It's a tough thing to try and get right - when programming for combat, you want enemies to miss some of the time, but not too often / too rarely, for example. I think the biggest problem that AP faces w/r/t AI is that they've gotten it in their heads to make stealth a viable gameplay option. It just doesn't do to make enemies realistic because if you slip up once, the entire mission becomes a disaster and you have to reload the game or fight all the way through it. Thus generally you make AI pretty fuckin' dumb - Enemies don't communicate with one another, they're relatively hard to alert and if you hide, eventually they will give up and continue their routine as though they never saw you in the first place.
