Technophobia
The development of technology is not exactly equivalent of a development of humans, it rather leads to losing humanity and dependence on new technology. So I think this world is similar to a ‘desert island’ in that people are unaware of their blind conformity toward technology and loss of their identity. In order to escape from this situation, I go to the top of the building and send a rescue sign. There, a phrase of warning the effect of future technology is written.
