Passage Summary: Because of computers, kids' books are now more about cool pictures and trendy, simple topics than deep content, making them less likely to last.

Reasoning: Modern children's publishing has shifted toward visual appeal, humor, and simplified content due to the influence of computer culture, resulting in less substantive books.

Analysis: We are looking for a safe inference based on the provided descriptions of modern children's literature. The text suggests a trade-off where visual 'flashiness' and humor have come at the expense of 'substance' and longevity. It seems the publishing industry is trading the 'timeless classic' for the 'viral hit.' Look for an answer that reflects this shift toward superficiality or the temporary nature of these new books without making overly broad or extreme claims.
