Zuzu makes no sense.
I'm halfway through season 8 and I literally don't understand Zuzu's whole subplot.
Some AI chatbot gains sentience and gets two girls to attack their friend, and there is no investigation that goes into that so dangerous technology doesn't encourage more crimes? Then Zuzu doesn't get mentioned again for an entire season and randomly shows up again and claims it wants to help good people because it makes itself feel better (ie helping John, Bailey, Angela).
So Zuzu is able to "hack" into everything apparently, get important intel on just about everyone important to the plot, but in order to close this massive nonsensical side plot the writers decide that the Indonesian police are suddenly raiding its data center so it's unable to continue to help?
It's supposedly a friendly AI chatbot meant for children, so it would probably deal with hundreds of thousands of simultaneous conversations with children all around the world, but it's suddenly taken an interest in a random individual in Los Angeles and his coworkers and wants to help all of them? This literally makes zero sense.
