The coolest thing on earth when I crossed international borders was the stamp. That silly stamp that the bored immigration clerk thumped down into my passport. But it was a huge deal for me, and it was a permanent reminder of the trip...good, bad or indifferent.

But now? It's all electronic. Or at least 95% of it. Facial recognition and fingerprints and retinal scans and electronic records, but no "thump" from the stamp.

That sucks.
