Can audiobooks replace print and ebooks? Will they?

Same here, Maggie. I can delve in a book, and isolate in it even in a pub.
Besides, I can't stand audiobooks. Even when learning a foreign language, to me the handbook to the method is more important than the audio material accompanying it.
When he turned 50, a male cousin of mine decided to learn English by listening to tapes while driving around. He is now 70, and still a dork in English. I advised him to open books.
On the other hand, I suppose audio books bring comfort to blind people.
Audio books for small children before they can read seem to be a good idea, although they cannot replace a parent lovingly reading a tale to their child.
Off topic, but somehow related in my mind, is "The Lost Language of Cranes" by David LEAVITT whose title is drawn from an anecdote, unrelated to the plot. A child is discovered in a New York tenement alone, neglected by his a teenage mother, a drug-addict. He can't speak, but communicates with the cranes on the construction site across the street, which he takes for sentient creatures.

Many people I know listen to audiobooks when they work.

Personally, I can't stand them! There are very few readers who will not put me right to sleep. I have heard two or three talented readers who are skilled in falsetto voice and are engaged in what they are doing and are lively and entertaining and bring the books to life; but they are SO RARE!

The vast majority of audiobooks I have inflicted on myself were read by horribly boring readers.

No, I prefer the voices in my own head, thank you.

It disturbs me when my brother tells me he's walking and listening to a book. Each should be isolated. Walk, feel the motion of your legs, muscles, the wind, people around, nature. When you read watch the curves of the letters, how neatly each lies next to the other. Why did the author use that word? Yes, it's perfect. Why is this sentence going over my head? I've read it three times. Ah yes, too many high falutin words, too many syllables in each, sentences are too long. I am a very slow reader. Audiobooks just whizz by. Like a bad lover.
