For example, jobs that are repetitive or high-risk may be replaced by machines that can perform the same tasks more efficiently and without putting human workers in danger. Additionally, AI may lead to job polarization, where highly skilled and highly paid professions like programming and data analysis thrive while low-skilled jobs that can be replaced by automation are eliminated. In the long run, the impact of AI on job displacement will depend on how quickly society adapts to these changing circumstances and how well we equip workers with the necessary skills to succeed in a rapidly changing job market.
Discrimination and bias in AI systems
Another important concern when it comes to AI is the possibility of discrimination and bias. AI systems can only be as objective as the data they are trained on, and unfortunately, much of the data used to train AI systems contains deep-seated biases. These biases can lead to perpetuating and even amplifying social inequalities, excluding certain groups of people, and hindering social progress. Additionally, AI systems that are not designed to recognize and correct their own biases can end up making decisions based on these biases, resulting in harmful outcomes for certain groups, such as women or people of color. Therefore, it is crucial to ensure that AI systems are designed with a focus on inclusivity, diversity, and fairness to prevent further discrimination and marginalization.
LeCun's contributions to the field of AI go beyond simply developing convolutional neural networks.
