I think it might be more insightful to say "laptops in the hands of students are worse than books in the hands of bad teachers".

A bad teacher can say "read chapter 7, there will be a test!" and the student can ignore the book, or vandalize the book or whatever. But when the student has a computer with an internet connection, they can vandalize the computer, ignore the website, or jump on an unrelated website.

I'm tempted to think that the laptop makes the situation worse. Some student who might have read part of the chapter out of pure boredom during classtime is now driven by dopamine to jump on the distraction.
