As technology continues to advance and society changes, some jobs may be done less and less. Here are some of the jobs that may be replaced by automation, mechanization or other technologies:

1. Production line workers: With the development of automation technology, many production line jobs will be replaced by robots and automated systems.

2. cashiers: as unmanned stores, self-checkouts and mobile payments become more popular, the need for cashiers will decrease.

3. Airplane and train pilots: With the development of self-driving technology, there may be driverless transportation in the future, thus reducing the need for airplane and train pilots.

4. Newspaper journalists: Changes in the news industry and the rise of new media have led to fewer job opportunities for journalists at traditional newspapers.

5. Bank tellers: with the popularity of online and mobile banking, the demand for bank tellers will also decrease.

6. Counter Attendants: The increased use of self-service equipment in the hotel, restaurant and retail sectors has reduced the demand for counter attendants.

7. Couriers: the use of unmanned drones will likely reduce the need for couriers.

8. Data entry clerks: with the development of automation and intelligent technology, many data entry tasks will be replaced by automated software and systems.

It is important to note that while these jobs may decrease, new job opportunities will emerge at the same time. Therefore, it is important to adapt to social and technological changes by constantly upgrading your skills and learning new technologies.
