No one ever knows what lies ahead on the road? What will the next generation evolve into? Or even what the weather will be like next (except for those with rheumatism~ haha). Anxious about company development, worried about children's future, afraid of being alone…, wanting to put down the heavy burden on their shoulders, yet no one can carry it. Opening the phone to find a solution, the things inside only make him more anxious—an explosion of information, the rapid changes of AI, interpersonal information exchanges, unread messages on LINE, plus various other communication apps… You've worked hard, friends!
