“An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered virus, nuclear war, inadvertent creation of a micro black hole, or some as-yet-unknown technology could spell the end of us.”

Simplified Meaning:

While natural disasters like asteroids and supervolcanoes are serious threats, humans today have other risks that the dinosaurs didn't have to worry about. For instance, scientists can create new viruses, and there is always the danger of a nuclear war. We also have advanced technology that could accidentally cause a disaster, like making a black hole that could swallow the Earth. These dangers are unique to our modern world and come from our own actions and inventions. Imagine a situation where a lab accidentally releases a virus that no one has immunity against, leading to a global pandemic. Or consider how nuclear conflict can cause massive destruction and long-term damage to the planet. It's important to be cautious and responsible with our advancements to avoid these potential catastrophes.
