They've placed more emphasis on hacking. I think this is because back in IW there was a huge thing about it but there was barely anything decent to hack apart from ATMs and Vending machines. I'm not sure about the AI being that dumb in normal atm but there have been a few moments recently (no spoilers) where the AI just straight up wouldn't stop being alarmed until i literally dumped the bodies on top of each other in a corner. If you get the thing to see how far cameras can view it changes per camera. I've had a few cameras that were long but their viewpoint was narrow whereas some were short and fat. So far it's been pretty good though.
I'm playing as an adaptive stealth character. I try taking bad guys out as silently as possible, but if I get caught I can still blast my way out of a situation. My load out: Revolver with explosive ammo, stun gun, silenced assault rifle with bullet lock on, and a crossbow with an enhanced scope. My augmentations are: Smart vision Punching through walls Weight enhancement 1 Picking up heavy objects Faster batter recharge 1 and 2 Extra battery 1 Cloaking 1,2,3 C.A.S.I.E Social Augment Hacking 2 Icarus landing system (may have forgot some) Bad ass moment: I was on the top floor of an apartment with three baddies below me. I jumped down activating the Icarus system. I landed on one instantly knocking him out and stunning the other two. I turned to my left and did a lethal take down. Turned and did the same to the other. Enemies above me noticed and started shooting. I activated my cloak and disappeared into the night. After three tries of course.

Yeah, there's plenty of stuff like that. Including a hidden surprise behind a wall in China. Just finished the game and watched all four endings. Pretty good game overall although I felt the end was a bit too rushed and could have more flavour added to it.
Finished it, endings a bit weak (before credits) but overall still an awesome game. Will play it through again in the future with a lethal route.
