5-Typist or word processor

 typing reports, letters, résumés, filling and classifying documents are tasks that will always be there but it will be done differently thanks to AI and automation.

4-Locomotive firers

not many workers are working in this field anyway, so it doesn’t surprise anyone to say that this job will soon vanish completely.  It will probably be one of the first jobs to disappear.

3-Librarians

 this one will disappear sooner than later for two reasons, the first one is that fewer people continue to read, buy books and attend to libraries. The second reason is because even those who are bookaholic,  are losing interest in physical books since everything is provided online. So, there will be no need for a librarian, if someone wants an information about some book they will find it automatically in the internet.
