One major ethical concern related to AI is bias and fairness. AI systems can inadvertently reinforce and amplify biases present in the data they are trained on, leading to unfair and discriminatory outcomes.
For example, an AI recruitment tool used by a major tech company was found to be biased against female candidates. The tool was trained on historical resume data that predominantly featured male candidates, resulting in the system favoring men over women for technical positions. This instance highlights the challenges of ensuring fairness in AI-driven hiring processes.
Another significant issue is seen in facial recognition technology, which has been criticized for its inaccuracies and biases. Research has shown that such systems often perform less accurately on darker-skinned and female faces compared to lighter-skinned and male faces. This discrepancy underscores the importance of using diverse and representative training data to prevent reinforcing societal inequalities.
To address these concerns, it is crucial to implement robust testing, utilize diverse datasets, and ensure transparent and accountable methodologies in AI development. Fairness in AI is essential for building trust and ensuring that these technologies serve all individuals equitably.

The Android activity lifecycle consists of several states: onCreate(), onStart(), onResume(), onPause(), onStop(), and onDestroy(). These states manage the activity’s creation, visibility, interaction, and destruction.
To handle configuration changes like screen rotations without losing user data or state, you can use the onSaveInstanceState() and onRestoreInstanceState() methods. onSaveInstanceState() is called before the activity is destroyed, allowing you to save data to a Bundle. onRestoreInstanceState() or onCreate() can then retrieve this data when the activity is recreated.
Alternatively, you can use the ViewModel architecture component, which is designed to store and manage UI-related data in a lifecycle-conscious way. ViewModel objects survive configuration changes, meaning they retain data even if the activity is destroyed and recreated.
