Robert Sloss predicted the iPhone in 1910
Well, more or less. Or is it an iPad? In 1910 Stoss published an essay called "The Wireless Century," intending to predict the world of 2010. In this world everyone carries around a "wireless telegraph" which:
1. Serves as a telephone, the whole world over.
2. Either rings or vibrates in your pocket.
3. Can transmit any musical recording or performance with perfect clarity.
4. Can allow people to send each other photographs, across the entire world.
5. Can allow people to see the images of paintings, museums, etc. in distant locales.
6. No one will ever be alone again.
7. Can serve as a means of payment, connecting people to their bank accounts and enabling payments (Japan is ahead of us here).
8. Can connect people to all newspapers, although Sloss predicted that people would prefer that the device read the paper aloud to them (not so much the case).
9. Can transmit documents to "thin tubes of ink," which will then print those documents in distant locales.
10. People will have a better sense of the poor, and of suffering, because they will have witnessed it through their device (not obviously true, at least not yet).
11. People will vote using their devices and this will empower democracy (nope).
12. Judicial testimonies will be performed over such devices, often from great distances.
13. People will order perfectly-fitting fashions from Paris; this guy should be in the Apps business.
14. Married couples will be much closer, and distance relationships will be closer and better.
15. Military targeting and military orders will become extremely precise.
The essay is reprinted in the Arthur Brehmer book Die Welt in 100 Jahren. The book is interesting throughout; a bunch of the other writers thought in 2010 we would be fighting wars with large zeppelins.I'm not even going to try predicting what will be the case for 2110.
