We humans are not immortal, so it’s important that we live on somehow after our bodies turn to worm food. As usual, the Japanese can help in their usual creepy way.
‘Oboe’ is designed to hang out with the elderly, so that it can absorb knowledge, experiences and, well everything that reminds you of your loved ones before they die. This way as much of their “essence” as possible will live on. You can see how the future might play out with “Oboe”. We continue to live, in a sense, in robot form.
We become the robot evil that is our downfall. Robots who remember being human. It’s a vicious circle.
