For years, many have feared that artificial intelligence (AI) will take over national security mechanisms, leading to human slavery, domination of human society and perhaps the annihilation of humans. One way of killing humans is medical misdiagnosis, so it seems reasonable to examine the performance of ChatGPT, the AI chatbot that is taking the world by storm. This is timely in light of ChatGPT’s recent remarkable performance in passing the US medical licensing exam.

For eight years I have studied digital nomadism, the millennial trend for working remotely from anywhere around the world. I am often asked if it is driving gentrification.

Before COVID upended the way we work, I would usually tell journalists that the numbers were too small for a definitive answer. Most digital nomads were traveling and working illegally on tourist visas. It was a niche phenomenon.

When you think about human evolution, there’s a good chance you’re imagining chimpanzees exploring ancient forests or early humans daubing woolly mammoths on to cave walls. But we humans, along with bears, lizards, hummingbirds and Tyrannosaurus rex, are actually lobe-finned fish.

Sixteen-year-old Karl is seen for the first time in my optometry practice. He was referred to me for a fluctuating vision problem. During his examination, I saw signs suggesting he may have diabetes, which could have explained the fluctuating vision. This suspicion became a reality when his family doctor confirmed the diagnosis. Karl’s world was turned upside down.

As an optometrist, I invite you to dive into a reality that should concern us all.
