Actually. Let me adress the issue in more depth, becouse it irks me that one of my players are publically saying it doesn't make sense in a setting i created.
One. Most of the world got fucked over hard. AI today is about as advanced as to being input, and simple output. To reach the kind of AI where you can have a multibranch, completely and utterly sporadic coversation is so far off it hurts. Now add the afformentioned world getting the shaft. YOu now have a industrial complex in shambles. Reserouces will be put in things that can save us; weapons and shelter and defence in general. The kind of programming you need to dedicate years for to make AI that complex, is not on priority list. What people will want is targetting systems, logistics models.
Oh. The places who were the cutting edge in intelligent robotics, such as Japan? They got pulverized. Japan was only retaken 6 years prior to IC. Where and when would they decide "Lets make a AI we can talk to".
There is then the problem of sitting in a mech, with eldricht strange alloys. Alloys that are semi-sentient and reacts to neural input. Metals that will drive you mad from prolonged exposure. MEchs that move far to smooth for something so big, becouse of said metals connection to its pilots mind. A AI would be distracting. It would not be able to affect the strange metal the way a human can. It has no purpose.
ALso, This is a group rp. I assume you joined becouse you wanted the interactions with others. COllabs are the pinnacle of that.
