This statement is true for many things that were part of everyday life a few decades ago, but have now almost completely disappeared. What was an integral part of the life of the older generation is often a mystery to the younger generation.

Objects that are almost forgotten today
Floppy disk: Once a symbol for data storage. It was the predecessor of CD-ROM, USB flash drives and the cloud. The floppy disk symbol is still used as a symbol for storage today, although few people know what it is.

Rotary dial telephone: In the days before smartphones, the rotary dial telephone was a symbol of communication.

Video recorder (VCR): Once the center of the home theater, it allowed you to record programs and watch movies.
Many of these things changed the way we live and work before more modern technologies replaced them
