Final answer:
Children in 2157 AD would likely find a printed book to be a curious and intriguing relic from the past, a tangible connection to the historical evolution of literary tradition and information transmission.
Step-by-step explanation:
Children in the year 2157 AD, having grown accustomed to a world where traditional schools have been replaced by advanced technologies and all books are digitized, would likely find the discovery of a printed book exceptionally intriguing. The tactile sensation of the pages, the distinct smell of paper and ink, and the novelty of interacting with a static, unchanging text that doesn't require a power source would be a rare and tangible link to a past when information transmission relied on physical media. In a future where screen time dominates and technology has seamlessly integrated into daily life, a printed book would stand as a curious relic that harks back to Gutenberg's days. It represents a bygone era that these children have never personally experienced, yet connects them to the long history of literary tradition and the evolution of technology.
