Hello World: Being Human in the Age of Algorithms

Hello World: Being Human in the Age of Algorithms is an intriguing and thought-provoking exploration of algorithms in our modern world. Written by Hannah Fry, a mathematician and data scientist, the book examines the implications of algorithms on everything from everyday decisions to life-altering ones.

Through careful analysis, Fry explains both the upsides and downsides of our increasingly algorithm-driven lives.


Fry’s book provides a comprehensive overview of algorithms and their impact on society. She begins by making the case for algorithms’ usefulness, showing how they can aid with decision making in ways that are both more efficient and more accurate than humans can do.

To demonstrate this, Fry uses examples from various areas such as healthcare, policing, finance, employment and education.


Fry also examines some of the positive aspects of using algorithms to make decisions. She highlights how they can help eliminate certain biases that people may have (such as gender or racial bias) when making decisions or evaluating candidates for positions.

Furthermore, she delves into the ways that algorithms can be used to increase fairness in systems – such as giving equal opportunities to those who are not traditionally given them – and overall increase efficiency in various industries.


While Fry does discuss the potential benefits of algorithms, she also shines a light on their potential risks.

She discusses how even though there are advantages to automated decision-making processes, there are also downsides that must be considered – such as potential errors or oversights due to lack of human input or oversight when it comes to complex decisions.

Additionally, she provides insight into how these automated processes could potentially create new forms of inequality by privileging certain groups over others due to their technical knowledge or access to resources that others may not have.


Hello World: Being Human in the Age of Algorithms is an engaging and informative read for anyone interested in understanding how data science is influencing our lives today and into the future.

Fry skillfully navigates both sides of the debate on algorithms – highlighting both their potential benefits while being mindful of their risks – and ultimately challenges readers to think critically about how we use technology going forward.
