The jobs you will eliminate are by their nature mundane and potentially dangerous. Yes, there will be higher unemployment, but only for a time.
Technology has been replacing since as far back as we have the written record. Civilization will go on and there will always be jobs. Yes, some workers will be too old or unwilling to change. But that is what we have welfare for and this is why people have children.
Please don't lose sleep over your job. You are freeing up the human talent to focus on pursuits beyond the efforts you are automating away.
