Augmented Reality (AR) is a technology that overlays virtual objects on top of the real world. This technology uses a device, such as a smartphone or tablet, to project digital images onto the physical world. AR enhances the real world by adding a layer of computer-generated content that can be interacted with in real-time.

Virtual Reality (VR), on the other hand, is a technology that immerses users in a completely virtual world. VR uses a headset or a set of goggles to create an immersive experience that simulates a real-world environment. Users can interact with this environment, often using a controller or a set of hand gestures.

The History of AR and VR

AR and VR have a long and storied history that dates back to the mid-20th century. The first known VR device was created in the 1950s, and it was a headset that used stereoscopic displays to simulate a 3D environment. This device was created by a cinematographer named Morton Heilig, who called it the "Sensorama."

In the 1960s, Ivan Sutherland, a computer scientist, developed a device called the "Sword of Damocles." This device was one of the first true VR headsets and was connected to a computer that generated simple 3D graphics.

The 1990s saw the emergence of consumer VR devices, such as the Virtual Boy from Nintendo. This device, which was released in 1995, used red LED lights to create a 3D effect. However, it was ultimately a commercial failure due to its limited functionality and the fact that it caused headaches and eye strain.

The first known AR device was created in 1968 by Ivan Sutherland and his student, Bob Sproull. This device, called "The Ultimate Display," used a head-mounted display to project 3D images onto the physical world. However, it was not until the 1990s that AR became a practical technology.

Advantages of AR and VR

AR and VR have numerous advantages that make them valuable technologies for a wide range of applications. One of the most significant advantages of AR and VR is that they can be used to create immersive learning experiences. For example, medical students can use VR to practise surgical procedures in a safe, controlled environment. Similarly, AR can be used to create interactive educational materials that enhance the learning experience.

AR and VR can also be used to create engaging marketing and advertising materials. AR can be used to create interactive product demonstrations, while VR can be used to create immersive brand experiences. These technologies are also useful for creating virtual showrooms, which allow customers to experience products in a virtual environment.

Another advantage of AR and VR is that they can be used to create realistic simulations. For example, architects can use VR to create 3D models of buildings, while engineers can use AR to visualise complex machinery. Similarly, VR can be used to simulate dangerous or inaccessible environments, such as deep-sea diving or space exploration.

Disadvantages of AR and VR

Despite their numerous advantages, AR and VR also have some disadvantages that must be considered. One of the most significant disadvantages of AR and VR is that they can be expensive to develop and implement. Creating high-quality AR and VR experiences requires specialised hardware and software, as well as skilled developers and designers.

Another disadvantage of AR and VR is that they can be physically uncomfortable for users. VR headsets can be heavy and cumbersome, and they can cause motion sickness.

In conclusion, AR and VR are two rapidly growing technologies with incredible potential in various industries such as education, marketing, and entertainment. Despite the high cost of development and implementation, AR and VR offer numerous advantages, including creating realistic simulations and immersive learning experiences. However, it is important to keep in mind that these technologies also have some disadvantages, such as causing physical discomfort for users. As these technologies continue to evolve, we can expect to see even more exciting use cases emerge, and it is exciting to think about what the future holds for AR and VR.

Key Highlights:

• Apple is nearing a historic $4 trillion valuation, boosted by advancements in AI and rising iPhone sales expectations.
• Its shares have jumped 16% since November, adding $500 billion to its market cap.
• Despite past criticism for being slow in AI, Apple is now integrating ChatGPT and AI across its apps.
• Analysts predict stronger iPhone demand and revenue growth in 2025.

A $4 trillion market capitalization is about to be achieved by Apple, making it the first business to do so. Thanks to optimism for its artificial intelligence (AI) breakthroughs, the tech giant's stock has risen 16% since November, increasing its market value by $500 billion.

Investors are encouraged by the company's recent AI advancements, such as the incorporation of OpenAI's ChatGPT into its devices and app suite. According to analysts, these improvements might trigger a significant "supercycle" of iPhone updates, which would increase sales in the future.

Currently valued at $3.85 trillion, Apple surpasses the combined stock market values of Germany and Switzerland. While its growth pace has lagged behind AI-focused companies like Nvidia, which saw an 800% stock increase in the past two years, Apple is catching up by bringing more AI-powered features to its products.

Challenges and Outlook

Apple has faced criticism for being slower than competitors like Microsoft and Alphabet in adopting AI. However, analysts expect iPhone revenues to bounce back in 2025 as Apple broadens AI features and increases availability in new regions.

Despite concerns over high valuations, many investors remain optimistic about Apple’s growth. Warren Buffett's Berkshire Hathaway has reduced its Apple holdings this year, citing valuation concerns, but others believe the company's long-term prospects justify its current price.

Potential risks include global trade tensions and economic factors like tariffs, but analysts expect Apple to navigate these challenges effectively, as it has in the past.

Looking Ahead

Apple’s dominance in the tech world and its ability to innovate are key reasons it is approaching this historic milestone. The company’s focus on AI could play a pivotal role in shaping its future growth.

Key Highlights

• WhatsApp will stop working on Android devices running KitKat or older versions starting January 1, 2025, due to outdated software limitations and security concerns.
• Affected devices include models from Samsung, LG, Motorola, HTC, and Sony released over a decade ago.
• Support for older iOS versions will also end by May 2025, requiring iOS 15.1 or higher for uninterrupted access.

Starting next year, WhatsApp will discontinue support for several out-of-date iOS and Android devices to improve security and roll out new features. The messaging app will no longer be available on Android phones running KitKat or earlier as of January 1, 2025. Likewise, as of May 5, 2025, iPhones running iOS versions lower than 15.1 will no longer be supported.

Why the Change?

Launched in 2013, Android KitKat is already more than ten years old and does not have the features required to cope with WhatsApp's latest updates. In the same way, outdated iOS versions present security threats and are becoming less compatible with contemporary software features. WhatsApp intends to concentrate on improving user experience and guaranteeing optimal safety for devices running contemporary operating systems by ending support for these platforms.

Affected Android Devices

Here are some of the Android devices that will no longer support WhatsApp:

Changes for iOS Devices

WhatsApp will require iOS 15.1 or later for both its normal app and WhatsApp Business as of May 5, 2025. Older iPhone models that are only compatible with iOS 12.5.7, such as the iPhone 5s, iPhone 6, and iPhone 6 Plus, will be the primary targets of this. To keep using the app, users are urged to update their handsets or move to newer models.

What Users Should Do

• Android Users: Upgrade to a device running Android 5.0 or later.
• iOS Users: Ensure their iPhones are updated to iOS 15.1 or newer.

Looking Ahead

The choice made by WhatsApp is indicative of its emphasis on security and innovation. To ensure that users have a seamless and safe experience, the company regularly updates the necessities for its app to keep up with the most recent developments in technology.
