As an AI language model, I don’t have access to real-time information or the ability to predict future events. I can provide you with a list of general surprising events that could potentially happen, but please note that these are purely speculative and hypothetical:
1. Discovery of intelligent extraterrestrial life.
2. A major breakthrough in renewable energy technology that revolutionizes energy production.
3. Development of a cure for a prominent disease or medical condition.
4. Successful implementation of universal basic income in a major country.
5. An unexpected political revolution or overthrow of a long-standing regime.
6. A significant technological advancement in transportation, such as an entirely new mode of transportation or hyperloop-like systems connecting major cities.
7. A major environmental catastrophe, such as an unprecedented natural disaster or ecological crisis.
8. A global economic event like a stock market crash or the collapse of a prominent financial institution.
9. A groundbreaking scientific discovery in the fields of physics, astronomy, or medicine.

Remember, these are speculative examples, and the actual events that unfold in 2023 will likely be different.
