Basics
and discuss the fundamental nature of algorithms, explaining that they are essentially a series of steps to accomplish a task. Kartik compares algorithms to recipes, such as those used by Amazon to recommend products based on user behavior. He emphasizes the importance of understanding algorithms at a high level to make informed decisions.
Algorithms, quite simply, are just a series of steps one follows to get something done.

By being aware of how algorithms function, users can better navigate their influence on daily decisions, from job interviews to mortgage approvals 1 2.
Impact
Algorithms significantly influence various aspects of life, often more than people realize. Kartik highlights that algorithms drive a substantial portion of decisions on platforms like Netflix and Amazon, and even in critical areas like medicine and education. He argues against the fear-mongering around algorithms, advocating for a balanced view that recognizes both their value and limitations.
Over a third of purchases at Amazon are driven by algorithms. Over 80% of our viewing activity on Netflix is driven by Netflix's algorithms.

Understanding the broad impact of algorithms can help mitigate undue fears and focus on leveraging their benefits while addressing their shortcomings 3 4.
Biases
Kartik explains that while algorithms can be incredibly useful, they are not immune to biases. These biases can arise from the data they are trained on, leading to issues in areas like courtroom decisions and job recruitment. He suggests that transparency and user control are essential to mitigate these biases.
The algorithms that are shown to have a gender bias, they do not have access to the gender of the person. They actually pick up other things that are correlated with these.

By understanding and addressing these biases, we can improve the fairness and effectiveness of algorithmic decisions 5 6.
Learning
Algorithms learn from large data sets, much like humans learn from experience. Kartik describes how algorithms observe patterns in data to make decisions, but this process can also lead to the amplification of existing biases. He stresses the importance of using diverse and unbiased data to train algorithms effectively.
If the data from which it's learning is not ideal, it learns from it. And it's very hard to prevent some of these things because we want them to learn from data.
