On social media recently I came across a video someone had posted from Ho Chi Minh City. It was of a central square, which looked familiar, and as the camera turned, I saw the Rex Hotel, where I had stayed in 1994. There were a few new additions – a Gucci store – but the high-energy scene of traffic and people and lights was just as I had remembered it. I recalled how I would stand on the hotel steps, taking it all in and wondering how I could describe it to readers back in Florida, most of whom had never seen such a show. And, watching the video, I realized that travel writers are now relieved of the responsibility of description, for the physical world is now all on film.
