1. Human brain adaptability is limitless, enabling excellence in new technologies.

The human brain's adaptability, known as neuroplasticity, is a remarkable trait that allows it to adapt to new situations and technologies. This adaptability is not limited by the emergence of new devices and AI systems, but rather, it has the potential to excel in these areas. This is also reflected in our computational systems, which demonstrate similar adaptability. The question is, what are the limits of this adaptability.

2. Human brain is a malleable, constantly adapting system.

The human brain is a complex, constantly changing system that adapts to the world around it. It's a combination of hardware and software, with different parts of the brain having different levels of plasticity, or malleability. This flexibility allows humans to absorb culture, language, and beliefs, and it's a successful strategy for survival. The brain learns through practice and physical changes in the circuitry, and even as we age, it remains malleable and can learn new tasks and remember new faces and names. The goal of the brain is to create an internal model of the world and understand how to function in it, and it's constantly reconfiguring itself to achieve this.

3. Brain adaptability and sensory substitution can enhance our abilities.

The brain's adaptability and ability to learn from new technologies make it a valuable tool for enhancing our abilities. Examples include brain-computer interfaces (BCIs) and Neuralink, which can improve the lives of individuals with paralysis or other neurological conditions. Sensory substitution, where the skin is used as a computational material to feed information into the brain, is a promising area of research. Companies like Neo Sensory are exploring sensory addition, such as picking up on infrared radiation or the magnetic field of the earth, to expand our oomveld, or the slice of reality we pick up on, by adding new senses. This technology has the potential to provide a more accurate perception of reality and bridge the gap between our current limited senses and the vast possibilities of sensing.

4. Pandemic forces reinvention, challenging our brains and shaping our future.

The pandemic has compelled us to redefine ourselves and discover new ways of doing things, which can be a positive experience as it challenges us to think creatively and adapt. Our brain is constantly evolving, influenced by both nature (genes and womb experiences) and nurture (life experiences). Our experiences shape our gene expression, shaping who we become. Taking care of children and providing them with good education and childcare is crucial for their development and future success.

5. Brain tribalism and illusions are influenced by external factors.

The brain, a complex machine with billions of neurons, is influenced by external factors and may create illusions that are useful for us. It is also susceptible to tribalism, where groups of people can engage in extreme behaviors due to their in-group bias. This tribalism can be observed in experiments where participants show a stronger response to seeing pain in their in-group compared to their out-group. However, when given a reason to care about their allies, their response shifts. This tribalism is not limited to humans, as studies on monkey troops on an island have shown similar behavior.

6. Neuroscience and specialized courts can revolutionize psychiatry and public policy.

The field of neuroscience is becoming increasingly important in psychiatry, offering valuable insights and interventions for conditions like schizophrenia and drug addiction. The current legal system, which treats all individuals equally, does not account for the unique characteristics of each brain. Specialized court systems, such as mental health courts and drug courts, can be implemented to address these issues. The process of injecting expertise into public policy often requires a county to run out of money and realize the need for smarter solutions. COVID-19 has highlighted the potential for government to make a positive impact and inspired young talent to enter government and revolutionize different aspects of it.

7. Human intelligence arises from brain interaction, AI lacks understanding and drive.

The human brain's intelligence arises from the interaction of all its parts, allowing for adaptability and learning from new experiences. This is in contrast to artificial intelligence systems like GPT-3, which lack the ability to understand context, nuances of human communication, and the drive for relevance and survival. While GPT-3 can generate content, it lacks the ability to fully understand the human experience and the various factors that influence our communication. The desire to survive is a fundamental aspect of human cognition, and AI systems lack this drive. Building AI systems that are closer to human cognition without the mortality and survival piece is an interesting speculation.

8. Embrace uncertainty, explore interests, and commit to passion.

The essence of life lies in the choices we make and the meaning we give to our experiences. It's important to embrace uncertainty and adaptability, especially for young people, as the future is unpredictable. Passion and inspiration can drive us towards our goals. The key is to stay open-minded, explore different interests, and commit to what sparks our passion. The concept of brain plasticity highlights the potential for different trajectories in life, but ultimately, we end up as the person we have become. The meaning of life is a question that can be approached from different perspectives, and it's important to constantly ask ourselves if there is something better we could be doing.
