Because of this, they exist in a grey area of society where there are still no clear rules or regulations to guide or monitor their development. The capabilities of machine learning and AI are highly attractive, and every country, corporation, and researcher wants to gain a strong position in this fast-growing field. In the race to become a major player, many may overlook or ignore the ethical issues involved in developing these technologies in order to stay competitive in the market. + +The author of the article clearly highlights these ethical concerns, such as hidden labour, bias in data and classification, and accountability and power. Many AI systems depend on thousands of low-paid workers who manually label data to train algorithms. Their work is often invisible, raising concerns about fairness and exploitation in the global tech industry. In addition, the data used to train AI models often carries social and cultural biases — related to gender, race, or culture — which can lead to unfair or discriminatory outcomes. + +Finally, there is the issue of accountability, as it is often unclear who should be responsible when AI systems make mistakes or cause harm — the developers, companies, or the technology itself. This lack of transparency and regulation creates serious ethical challenges. Therefore, while AI offers great potential, it is crucial to ensure that its development and application are guided by strong ethical principles and social responsibility. ``` diff --git a/02_activities/assignments/DC_Cohort/assignment-two_Section 1_prompt 1.drawio.png b/02_activities/assignments/DC_Cohort/assignment-two_Section 1_prompt 1.drawio.png new file mode 100644 index 000000000..dc6bb4710 Binary files /dev/null and b/02_activities/assignments/DC_Cohort/assignment-two_Section 1_prompt 1.drawio.png differ diff --git a/02_activities/assignments/DC_Cohort/assignment-two_Section 1_prompt 2.drawio.png b/02_activities/assignments/DC_Cohort/assignment-two_Section 1_prompt 2.drawio.png new file mode 100644 index 000000000..29bb53467 Binary files /dev/null and b/02_activities/assignments/DC_Cohort/assignment-two_Section 1_prompt 2.drawio.png differ diff --git a/02_activities/assignments/DC_Cohort/assignment2.sql b/02_activities/assignments/DC_Cohort/assignment2.sql index 5ad40748a..9455ff9d9 100644 --- a/02_activities/assignments/DC_Cohort/assignment2.sql +++ b/02_activities/assignments/DC_Cohort/assignment2.sql @@ -20,6 +20,12 @@ The `||` values concatenate the columns into strings.
