The computer book section that once dominated bookstore walls—with its iconic animal covers for languages like Perl and Python—is shrinking fast. Through the first nine months of 2023, computer book sales dropped 16.9% year over year, and publishers have quietly stopped reporting the category altogether.

ChatGPT commands over 900 million monthly active users, while GitHub Copilot reached 4.7 million paying subscribers by January 2026—a 75% annual increase. Stack Overflow's question volume has fallen to 2008 levels as programmers get instant answers from AI assistants.

The physical act of transcription made concepts stick. AI provides perfect explanations on demand, but without the discipline of manual repetition.

The kid learning to code through conversational agents today builds at a higher abstraction level than previous generations. They're not worse programmers—just different ones, shaped by tools that answer instantly rather than requiring the patient work of typing through 400 pages of examples.
