AVICII’S LIFE AFTER REHAB

Once he completed his month in rehab, Avicii seemed to have a new outlook on life. He was meditating regularly, reading about the collective unconscious, and got a puppy. After not performing for a long period of time, he returned to the stage in 2016 at Miami’s Ultra Music Festival. It was announced a few days after this gig that he would not be performing live anymore. Avicii chose to not perform so that he could focus on bettering his mental health.

Despite appearing to have new-found stability, Avicii still struggled to deal with his mental health issues. While continuing to suppress the anxiety and depression that he frequently felt, Avicii also started to become disinterested in his music career. During this time, he was smoking and drinking on occasion which may have resulted in a resurgence of his disassociation feelings.

He told Tereza Kacerova, his girlfriend at the time, “What if everyone around me is just a projection in my mind? Sometimes I just think these things. About how nothing really matters.”

Avicii started to focus heavily on meditation which he found to be helpful in clearing the “nonsense” from his mind. He believed that a deep form of meditation taught by Maharishi Mahesh Yogi was a way to exercise his brain which he had decided would lead to his happiness. Despite this form of meditation typically being done in 20 minutes increments, Avicii would sometimes spend full days meditating in an attempt to reach enlightenment faster.

What can be inferred about Avicii's mental state after rehab?

Read the following passage about Artificial Intelligence and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are designed to think, learn, and adapt. AI is applied in various fields, including healthcare, education, transportation, and entertainment. Technologies such as machine learning, natural language processing, and robotics enable AI systems to perform tasks like diagnosing diseases, personalizing education, and even driving autonomous vehicles.

One significant benefit of AI is its ability to enhance efficiency and accuracy. For example, AI-powered systems can analyze vast amounts of data faster than humans, identifying patterns and trends that might otherwise go unnoticed. In healthcare, this means earlier diagnosis and improved treatment plans. In transportation, AI contributes to safer roads with the development of self-driving cars.

Despite these advantages, AI poses several challenges. Concerns include ethical issues, such as bias in algorithms, and the potential loss of jobs due to automation. Cybersecurity risks are also heightened as AI systems become more integrated into critical infrastructure. Addressing these challenges requires transparency, regulation, and collaboration among stakeholders.

To maximize its benefits, society must approach AI development responsibly. Governments, private organizations, and researchers are working together to create ethical guidelines and ensure that AI serves humanity’s best interests. As AI continues to evolve, it holds the promise of transforming the way we live and work.
