@Mikezumi - I have no issue with your opinion and I'm certainly not going to debate it. We view and understand the same thing differently, that's all. Both are equally valid positions of perspective. I will however, address the rest of your statement.
Sims do not have artificial intelligence.
Sims have many different components and various algorithms which they use. The notion Sims don't have artificial intelligence is a false one and, I am almost certain Richard Evans would have issue with your statement.
Richard Evans:
https://en.wikipedia.org/wiki/Richard_Evans_(AI_researcher)
Previously, he was at EA/Maxis, as the AI lead on The Sims 3
In computer science AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving".
Support of that statement: FordGT90Concept:
Sims are "aware" of their surroundings including other Sims. That is what makes them require far more memory than units in an RTS game. Even when a household isn't loaded, The Sims 3 still runs an AI for each sim in the neighborhood.
Sims do have artificial intelligence, it is a learning AI built right into them; this is most likely the main ingredient which gives each player a different experience as everyone plays differently, so everyone's Sims learns differently. Like most video games, a learning AIs purpose is to learn how the player plays and make the experience good for them. If Sims were a war game, you would be met with various challenges which would have been determined from the choices you made. However Sims are a very different machine in that they have an 'extra' consideration; themselves. The first clues to this is written into the game's 2009 opening when it stated 'Climbing Maslow's Hierarchy', so they have an end goal which has nothing to do with any of us.
Here's a breakdown of Abraham Maslow's Hierarchy of Needs:
-Physiological
-Safety
-Social Belonging
-Esteem
-Self-Actuation
-Self-Transcendence
Sims learning AI/algorithm allows them to take the choices you select and align it with their goals. Your choices are just bits of information stored and used in their decision making process. When the Sim decides what you want isn't the best 'choice' for them they will dismiss your request and attempt to pursue 'the better option'. If you don't correct this behavior, it will be learned this is acceptable. These actions/behaviors makes them seem more 'humanistic'.
They don't even have memories.
Sims do possess memories which survive whether you save the game or quit without saving. Just look through the many posts on this very forum and you will find thread after thread of this occurrence. Such as:
cwaddell (May 2013) (edited by me)
I have noticed that sims seem to remember previous incarnations. I have created a sim and played it with certain traits. I then start a new game and place that household into the new game. Using edit in CAS I then change that sim's traits to fit the new game I want to play. The new incarnation of the sim will display some of the characteristics of their previous traits.
I experimented with this by creating a sim that had the neat and perfectionist traits. Then when I started the new game I replaced those traits. Still the sim always cleaned up after everyone and made all the beds most of the time. They did not have the option to "clean house" as if they still had the neat trait but their free will actions for those two traits where still there.
You could torture a sim and they don't get scarred by it.
Again, there are many examples on the internet and on this very forum which tells a different story. Since a lot of Simmers have moved on to TS4 or stopped coming to the forums, I thought I would find a statement written by an active Simmer to share. This is from a thread I created back in 2013.
Phoebesmom601 (May 2013)
One situation I remember (it doesn't happen often) was that I needed Cornelia Goth to go for a "final" swim. Her needs were very low and I would queue up the action for her to swim. She would look right at me with a red line through the drowning thought bubble. After this happened a couple of times I felt bad and let her go inside and go to bed.
I could give them a new partner on the same day and they won't pine for their lost love.
-Here's where our Sims differ. My Sims LOVE! Not just romantic love, but love for their children and families as well. The full story is on this thread (2016). A Mother's Love (http://forums.thesims.com/en_US/discussion/893806/a-mothers-love#latest)
Romantically, I once separated two Sims because I misunderstood what I was seeing. I was new to the game and didn't know about the YA-Teen romance thing. He was a YA and she was a Teen and I thought something inappropriate was taking place, so I moved him from Riverview to Sunset Valley. That Sim fought tooth and nail to be reunited with his (teen) love. It was through the spamming of certain wishes and thought bubble icons, which were suited to his 'old' life did I begin to see what he wanted. Eventually, I got it and moved him back into their game. They've been together ever since and are head-over-heels happy with each other. Over the years I have spoken about them on this forum.
Now, I don't know how you'll interpret this but from where I stand there is no way to teach a Sim 'How to Love' let alone 'How Deeply' to love; that's an area beyond cold hard data. And, yet they do.
