Li-Fi (Light Fidelity) and Wi-Fi (Wireless Fidelity) are both technologies used to transmit information wirelessly, but they work on completely different principles. These are some main advantages Li-Fi has over Wi-Fi :

1. Speed: Li-Fi can give a blazing transmission of up to 224 Gbps in data transfer—miles better than Wi-Fi, which can at most run only up to 100 Mbps and, in most cases, just a few Gbps. It is so because visible light works at a higher frequency than radio waves, used under the wing of Wi-Fi.

2. Bandwidth:The bandwidth for Li-Fi is enormous with the visible light spectrum being 10,000 times larger than the radio spectrum, such that this is 10,000 times larger. Implausibly, this tries to reduce the congestion problems other than the problems experienced with Wi-Fi in relatively high-density environments.

3. Security: On the other hand, since the Li-Fi signals are within the illumination area, they are further secure from passing through the walls where there might be unauthorized access. This removes the risk of eavesdropping since the Wi-Fi signals pass through walls.

4. Interference: With electromagnetic interference from devices like Wi-Fi, which might not be interfered with by microwaves or cordless phones, hence Li-Fi fits for places vulnerable to such interference like hospitals and airplanes.

5. Availability: Li-Fi can work in environments where radio frequency communication is not ideal or allowed. As long as there is light, Li-Fi can provide connectivity, even in underwater environments or other places where Wi-Fi is not feasible.

Overall, for Li-Fi, the properties of speed, bandwidth, security, reduced interference, and versatility make an interesting alternative or complement with Wi-Fi in all kinds of applications.

Artificial Intelligence (AI) – The idea and development of computer systems able to perform tasks normally requiring human intelligence, such as visual perception, speech recognition, decision-making. It encompasses several tools such as machine learning, neural networks, natural language processing and robotics.

Types of AI:

1. Narrow AI (Weak AI): Specific use – e.g., facial recognition, or language translation. One-operation-only systems: These are the simplest because they operate in isolated operation with too small constraints.

2. General AI (Strong AI) Any hypothetical artificial instantiation of humans ability to perform any cognitive function that a human being does. It is capable of understanding, learning and executing knowledge in many spheres.

3. Artificial Superintelligence (ASI)The next level of AI that us more intelligent than the best human across basically every field; scientific creativity, general wisdom and social skills.

AI Creating Wealth:

Artificial intelligence itself can create an immense boost in human wealth, simply by unlocking innovation and productivity. AI applications can automate monotonous tasks, speed up the processes and lower costs of operations as well assist decision-making through data analytics. In fact, in fields such as healthcare AI might help identify diseases earlier than ever before and offer personalized treatment, which will reduce the cost of health care while increasing life expectancy. Finance: AI algorithms can improve investment strategies, increase risk management efficiency. AI will be able to breathe life into economies by introducing new AI development, maintenance and application industries contributing job opportunities. For these reasons, AI can make society wealthier by making it more efficient and enabling new economic activities.
