> How can we make books cool without pretending all this tech didn't exist?

You don't need to pretend it didn't exist, you need to legislate and ensure that access to it is cut off uniformly for developing minds. We already see the emergence of this kind of legislation with Australia enforcing a ban for social media under 16s; and other countries in the process of legislating ones.

I happen to favor this approach because "pretend it doesn't exist" strategy doesn't work for addictive things that are left lying around the house for kids to access. If society in general can prevent children from getting access to alcohol before 21, there's no particular reason the same can't be done for addictive "social" media algorithms.
