Thanks so much for reading my column, but I have to ask: are you a thief? I need to know because Technology Review reserves the right to sue you if you reproduce this intellectual property without our express, written approval. By the way, this publication uses "smart paper" with patented steganographic technologies explicitly designed to track unauthorized scans or photocopies of my column.

We've also placed a radio frequency ID tag inside the cover that can track how much time you've spent with the magazine, where you read it, and whether you ultimately save, discard, or share it. Our advertisers love that feature; we're sure you'll grow to love it, too. After all, shouldn't an innovative magazine about innovation create innovative ways to track its readership? Enjoy.
