This week began with an end of an era — Tim Cook’s, who signed off from his final Worldwide Developers Conference on Monday. Cook had given his first keynote way back in October 2011, after taking Apple’s reins from the legendary Steve Jobs. With John Ternus stepping in his shoes soon, the event saw Cook wrapping up with Apple’s vision of AI in the future. Siri AI was introduced and Apple Intelligence was expanded, even as AI agents entered the Passwords app. The coming weeks and months should be an exciting time for Apple fans with iOS 27 in beta, before its rollout in September — when Cook rolls the dice on Ternus and bids farewell as CEO.

Leaks around the iPhone 18 Pro range — which is also set to be unveiled in September — continued to surface this week as well. While one claimed the upcoming Pro range may start $100 upwards from the last generation, another indicated that might not be the case, and Apple may absorb rising productions costs but charge for advanced AI features.

In other important news, OpenAI introduced Lockdown Mode in ChatGPT to help protect data against theft, Instagram added a long-requested Reorder Grid feature, Telegram revived Wear OS smartwatch support, and Realme launched the P4R 5G with a massive battery under the hood.

Saving money is only the first step toward building wealth. The most important thing is making informed investment decisions and understanding the power of compounding. Sometimes, people are confused and eager to know how quickly their money can grow. That’s where the Rule of 114 comes in, offering a simple way to estimate how long it may take for an investment to triple in value.

The Rule of 114 is a widely used personal finance formula that helps investors calculate the approximate number of years required for their investment to grow threefold at a fixed annual rate of return. Based on the principles of compound interest, the rule provides a quick estimate without the need for complex financial calculations.

What Is the Rule of 114?

The formula is straightforward: 

Time to Triple (Years) = 114 ÷ Annual Rate of Return (%)

By dividing 114 by the expected annual return, investors can estimate how many years it will take for their investment to become three times its original value.

For instance, if an investor puts Rs 1 lakh into an investment earning a steady 6% annual return, the Rule of 114 suggests the corpus could grow to approximately Rs 3 lakh in around 19 years.

How It Works

At a 10% annual return, Rs 1 lakh could triple to Rs 3 lakh in about 11.4 years.

At a 12% annual return, the same amount could grow threefold in roughly 9.5 years.

At an 8% return, the tripling period would be approximately 14.25 years.

Benefits of Using the Rule of 114

The Rule of 114 is a useful tool for long-term goal setting. It can help individuals estimate the time needed to build a retirement corpus, save for a child’s education, or accumulate funds for major purchases such as a home.

The rule allows investors to compare different investment options based on their average expected returns and assess whether their financial goals are realistic.

Another advantage is its simplicity. Unlike detailed financial calculators or spreadsheets, the Rule of 114 provides a quick estimate that can be worked out mentally.

Limitations of Rule of 114

Despite its usefulness, the Rule of 114 comes with certain limitations.

Assumes constant returns over time: It assumes that investments generate a constant annual return throughout the investment period. In reality, market-linked investments such as stocks and mutual funds often vary from year to year due to market fluctuations, economic conditions, or company performance

Ignores the impact of taxes and inflation: The formula also does not account for taxes, inflation, investment costs, or changes in purchasing power. As a result, actual outcomes may differ from the estimated figures.

Not ideal for simple interest-based products: The rule is designed for investments that benefit from compound interest. It may not provide accurate results for instruments that offer simple interest.

In a nutshell, Rule of 114 offers a quick and practical way to understand the impact of compounding and estimate when an investment could potentially triple in value. While it should not replace detailed financial planning, it encourages objectivity and discipline in investing and helps individuals stay focused on long-term economic growth rather than short-term market fluctuations.

Anthropic issued a statement on Saturday after the United States government ordered the suspension of access to its Fable 5 and Mythos 5 models for all foreign nationals. 

The Donald Trump administration has cited national security concerns over the directive, noting that it applies to foreign nationals both inside and outside the United States, including Anthropic employees who are not US citizens.

As a result, Anthropic said it must immediately disable access to Fable 5 and Mythos 5 for customers to comply with the order. The company clarified that access to all other Claude models remains unaffected.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

“We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible,” the AI major said.

Why The US Govt Went After Fable 5, Mythos 5?

The move comes just days after Anthropic launched Fable 5 and Mythos 5, which it described as some of its most advanced AI models. Fable 5 was notable because it is Anthropic’s public version of more advanced Mythos 5, released with cybersecurity safeguards and restrictions to prevent misuse. 

The models followed the release of Claude Mythos Preview in April, which drew attention for its enhanced cybersecurity abilities. On the release, Anthropic clarified that it planned a limited rollout, making the model available only to selected companies through its Project Glasswing.

Fable 5 can perform strongly in areas such as coding, research, reasoning, vision and knowledge work, according to the company. Because of its powerful capabilities, Anthropic has added safety measures that limit responses in high-risk areas such as cybersecurity.

Anthropic has so far ​limited its access to a group of about 200 organisations including ⁠the US government under the Glasswing program, after announcing in April that ​Mythos had uncovered thousands of software vulnerabilities.

Mythos 5 uses the same core technology as Fable 5 but with fewer restrictions. “Mythos 5 is the same underlying model as Fable 5, but with the safeguards lifted in some areas. Mythos 5 will initially be deployed through Project Glasswing, in collaboration with the US government, as an upgrade to Claude Mythos Preview. It has the strongest cybersecurity capabilities of any model in the world,” the company announced earlier.

Despite Anthropic’s assurances of safeguards for certain areas, the US government has banned these models for foreign nationals over cybersecurity concerns. The models’ ability to detect vulnerabilities and accelerate innovation makes them strategically important. 

According to Anthropic’s statement, the US government appears to have blocked access to Fable 5 and Mythos 5 over concerns that users could bypass the models’ safety safeguards through a jailbreaking technique. This could result in users potentially having access to more powerful cybersecurity capabilities than intended.

But, Anthropic has argued that the demonstrated vulnerabilities were “minor” and that it is working to resolve the “misunderstanding” with the officials.
