Why not typing drill books?

Have you heard about typing drill books? Why is it not used nowadays?

Hi!

The drawbacks of typing drill books are obvious like they don’t implement the best practices of recent research. They don’t use the strengths of the computer to engage and motivate students with colorful graphics, gamification, sound and music, or personalized feedback. Also, they are completely manual, with no automated testing or grading, no monitoring of real-time progress, no capacity for statistical reporting.
