I don't expect printed maps to be around in maybe 10 years. The more that pilots use GPS, the less printed maps will be sold, and the cost of producing them will increase. The increased costs will be passed onto customers, which means even less will be sold.
It's the same with newspapers and printed books. Newspaper sales are falling by 10%-30% annually. Which means the cover prices go up faster than inflation to cover costs, and results in the circulations dropping even quicker. Very few newspapers will be around in 10 years time (probably just the Sun and Daily Mail!) and many will have closed within 5 years. Printed book sales fell 9.8% last year as digital sales increased.
The less paper that is used, the more it will cost to manufacture. A wholly paperless society is only a matter of time.
