Why did they get rid of chalkboards?

Whiteboards provide a more contemporary look, easier maintenance (though markers can dry out), and use dark writing on a light background, similar to books and screens, enhancing clarity and minimizing dust issues for computers.

Why are chalkboards not used anymore?
