In the 1990s, a friend told me he'd read an article that said in the future no one would buy books. Instead, people would have this amazing device that could turn into any book just by asking for it. That sounded impossible to me, and I didn't connect it with the computer on my desk with its giant monitor, bulky processing unit, and dial up Internet connection that made odd pinging noises.
Yet here we are in 2017, and I both read books on Kindle and publish my novels in numerous ebook editions. (I still read paper books, too, as do many people, so that part hasn't completely come true.)
Publishing seems to change by the minute, and advances like cars with built-in capacity for streaming audiobooks and virtual and augmented reality technology will no doubt will cause further evolution. So this Friday, my recommendation is the podcast/video episode from The Creative Penn on the future of publishing.
