The infrastructure exists in Sims 4 to create intelligent Sims it's just not utilized. All Sims instantly go play on the computer, or go play Horseshoes. There is no diversity it what activities a Sim chooses because they used a simplistic one size fits all system for attracting Sims to certain objects. They are also 99% oblivious to the world around them which is why when a Sim begins preparing a meal, the others will go get a snack out of the fridge. Maxis didn't apply a trigger alerting Sims that another Sim was performing an activity. This simple system would have dramatically improved the AI. If two Sims are in the same room they should know what is happening. For instance "That Sim just went into the bathroom. I won't barge in." or "That Sim is preparing a meal. I'll wait." or "My spouse just went to bed. I'll join them." or "My teen age son is making out with his girl friend, that's inappropriate!" However they did manage to apply triggers in the dumbest ways. For instance, your Sim goes over to their boy friends house, and begins cooking him a meal....here he comes saying, "That's inappropriate! If you keep that up you'll have to leave!" REALLY!? That's the one thing Maxis decided was important? Let's say that was in any way useful, why still does it ignore relationship status!? Sims are completely oblivious unless they can verbally assault someone. :neutral:
