  • Global connectivity: The internet has created a more interconnected world.

4.2 Negative Impacts

  • Job displacement: Automation and AI are replacing some human roles, especially in manufacturing and administrative work.

  • Digital divide: Not everyone has equal access to technology, exacerbating socioeconomic inequalities.

  • Privacy concerns: Data breaches and surveillance have sparked debates about personal privacy.

  • Mental health: Social media can contribute to anxiety, depression, and social isolation.

5. Emerging Technology Trends

5.1 Quantum Computing

Quantum computers use quantum bits (qubits) to perform complex calculations much faster than traditional computers. Potential applications include:

  • Drug discovery

  • Cryptography
