In a conversation with her 11-year-old child, a parent reflects on the bygone era of encyclopedias and how they were once indispensable tools for knowledge. The discussion reveals a generational gap in understanding information access, as modern children are accustomed to instant online resources like Siri, ChatGPT, and YouTube. This shift highlights the rapid evolution of technology and its impact on how we acquire knowledge.

As the parent explained, encyclopedias used to be physical books organized alphabetically. For instance, if one needed information about the Revolutionary War, they would turn to book R or RA-RO, depending on the encyclopedia's size. These books provided concise yet comprehensive summaries, often spanning just two pages. Despite their limitations, encyclopedias were considered invaluable sources of information, though not every household could afford them due to their high cost, typically around $500.

Interestingly, salespeople would visit homes to persuade families to invest in these sets. Dressed professionally, they offered what was then seen as an essential educational tool. To today’s youth, this concept seems absurd, much like the idea of dinosaurs roaming the streets. It underscores the dramatic transformation in accessing information over a relatively short period.

This reflection prompted the realization that technological advancements have reshaped our world profoundly. What once required a trip to the library can now be achieved with a voice command or a few keystrokes. This shift not only changes how we learn but also alters our perception of what constitutes valuable knowledge.

The dialogue between parent and child serves as a reminder of how swiftly the world evolves. Concepts that seem outdated today were once revolutionary. As new technologies continue to emerge, it is fascinating to consider what future generations will find incomprehensible about our current practices.
