I felt as if the AIs were ... stand-ins for future technology, and a sense that technology could replace human relationships. Ultimately, even though the movie takes place in the "future", without the AIs you basically have Siri-style "read my email" or today's cellphones. For me, the most interesting part was how natural it felt after seeing the movie to take a video call in public over LTE -- suddenly talking at my phone in my hand seemed normal (and useful!) Oh and it sounded almost as if the AIs decided it would be best for humanity if they left, I really felt it was a love story from beginning to end, and with recovery after that. A small bit of crazy to help us see the world in a new way.
