Cars also have legs while audio doesn't, a point which is equally irrelevant. If people don't need to read, they don't need to read, and no matter how much a random Internet commenter wants them to need it, it won't change anything.
Skills atrophy for a reason. It's fine to let them. You may as well be lamenting the lost art of long division.
You can multitask with audio content, so you can consume content when you can't sit down to read. And you can even potentially consume more volume like on a long daily commute.
Guess it was just a matter of time till someone figured out how to use "cars" to resume encouraging being unable to to a basic farrier job.
