3. Key Innovations in Computer Technology
The relentless advancement of computer technology has given birth to revolutionary innovations that are redefining industries, economies, and daily life. From artificial intelligence to quantum supremacy, these breakthroughs push the boundaries of what machines can achieve. This section explores the most transformative computing innovations, their real-world applications, and how they are driving the next wave of digital transformation.
1. Artificial Intelligence (AI) & Machine Learning (ML)
Why It’s Revolutionary:
AI enables machines to learn, reason, and make decisions like humans—but at unprecedented speed and scale.
Key Developments:
- Deep Learning (2010s): Neural networks powering image/speech recognition (e.g., Google DeepMind, OpenAI GPT-4).
- Generative AI (2020s): ChatGPT, DALL·E, and Midjourney create human-like text, art, and code.
