I have an iPad. One of my sisters has an iPhone. Lately, instead of talking on the phone we video chat with FaceTime. It is almost as good as having my sister here for a visit. Way back when we were kids, the idea of video chatting was science fiction. Now it's a reality.
The amazing thing is that so many inventions were dreamed up in fiction. Most readers are familiar with the gadgets Jules Verne and H.G. Wells wrote about that were able to be produced much later when technology caught up. However, I found an incredible site on the web that details many more technological wonders that were dreamed up by novelists who were way ahead of their time.

This compilation will show that ebooks were thought up in 1961 by Stanislaw Lem. Frederik Pohl wrote about cellphone voicemail in 1965. Poul Anderson wrote of laser rifles in 1966.
So though truth may be stranger than fiction, fiction writers are rather clever when it comes to devising useful tools that people need.
Thanks to fiction writers, my sister and I can talk to each other in real time. I love those fiction writers!
