A changing world and the human brain
The world is changing fast because of artificial intelligence and new technology. Many people feel overwhelmed and wish they could upgrade their thinking ability to keep up.
Our brains have not changed much since ancient humans. In fact, research suggests that human brains may have become slightly smaller over the last ten thousand years. Even so, the brain still has strong potential to adapt and grow with the right habits.
Why neuroscience matters in the AI age
AI systems are built using ideas from neuroscience. Scientists studied how the brain works and used that knowledge to create modern intelligent systems.
Now researchers are looking back at the brain to understand how humans can improve thinking skills. This creates a two way connection between technology and biology that can help people strengthen decision making and creativity.
Hannah Critchlow and the idea of mental flexibility
Neuroscientist Hannah Critchlow from the University of Cambridge explores this idea in her book The 21st Century Brain. She focuses on the mental skills people need to succeed in a world shaped by AI.
She explains that she wrote the book for personal growth as well. She also wrote it to help older generations keep their minds active and to support children in developing strong thinking abilities early in life.
Critchlow highlights mental flexibility as one of the most important skills for the future. It helps people adjust to change, solve problems, and make better decisions in uncertain situations.
Flipping the idea of intelligence and AI
Critchlow suggests a simple shift in thinking. Instead of only focusing on how AI is changing society, people should also focus on how neuroscience can improve human thinking.
AI comes from studying the brain, but humans can also learn from AI development. This approach can help people unlock stronger cognitive abilities and use their natural intelligence more effectively.
How to future proof your brain
Simple lifestyle choices can support brain health and creativity. Spending time in nature, for example, can improve focus and help new ideas form more easily.
Learning new skills, staying curious, and practicing flexible thinking can also support long term brain health. These habits help the mind adapt to rapid changes in technology and society.
