u can say how robots are seemingly taking over our world and this is our one and only world; humans created these robots yet these robots are gonna soon take over our places in society ------ soon we'll be worthless while the robots become priceless to mother earth; our past actions to make the world a better one will all be futile as we have no longer any stand in the world with the existence of robots.
