In the past, money was more important than time and it was natural to take the time to save money. However, these days, time and money have become equally precious, with time perhaps becoming even more precious than money. As a result, there is a growing number of people willing to spend money to gain more control over their time. This desire for efficient use of both money and time is leading to changes in various aspects of life.

we pointed out that AI cannot self-evaluate whether the results it produces are good or bad. The ability to reflect on oneself is called “metacognition,” and only introspective humans have it. In the end, only humans who can reflect on themselves will be qualified to put the finishing touches on AI’s creations

For example, if someone is a singer, it’s not just about having a good singing voice but also being well-mannered, coming from a well-off family, and showing signs of being nurtured with love. For those who are wealthy, it’s not enough to have money; they need to create wealth while contributing to personal development, earning the envy of others. We refer to people who aspire to be perfect in all aspects, including appearance, education, assets, career, family background, personality, talents, and more (which can be more than six), as “hexagonal humans.”

The price of the same product can vary significantly depending on when, where, how, and by whom it’s purchased, and suppliers and distributors can strategically set these prices. We refer to this approach as a “variable pricing strategy.” This strategy involves a methodology that can generate demand that previously may not have existed by presenting a multitude of various prices rather than a single fixed price. Thanks to the variable pricing strategy, the market paradigm is shifting from the traditional “one price for one product” model to “numerous prices for one product.”

In essence, with the advancement of IT technology, consumers’ access to pricing information has increased, while the influence of value-driven consumption has grown significantly. This has underscored the importance of AI-powered pricing functions, capable of real-time calculations involving numerous variables.

The desire for play has always been a part of human nature, but there’s something distinctly modern about the way people pursue fun today. The most significant shift is the incredible diversity and brevity of what people find enjoyable. Notably, platforms like TikTok, with its incredibly successful 15-second format, as well as Instagram Reels and YouTube Shorts, have embraced the trend of releasing short and engaging content.

More fundamentally, it can be seen as a reaction to the performance-driven mindset that has intensified since the COVID-19 pandemic. In dopamine farming, the key word is “just그냥,” reflecting the younger generation’s values of living life in a carefree manner. It represents a deviation towards fun in response to the societal pressure to lead a serious and demanding life.

The role of the household leader isn’t set in stone, but adaptable to different circumstances. There are men challenging the conventional idea that men should fit a certain mold. Just as women, raised as beloved daughters, pursue education and careers, they too understand that men must not only work but also fulfill multifaceted roles as husbands, fathers, sons, and sons-in-law. This context gives rise to the emergence of “millennial husbands,” who grapple with the demanding reality of balancing work and childcare responsibilities.

In other words, spin-offs are a way to diversify and make your business more flexible by gradually shifting the center of gravity of the core business. In 2021, the business environment was shaken to its core by the prolonged COVID-19 pandemic, and some industries were forced to pivot. However, in an endemic era, where the pandemic has subsided and new business opportunities, including artificial intelligence, are emerging, spin-offs are a less risky and more stable strategy that allows for diversification while maintaining a business’s core.

Spin-offs are a form of tuning, a process of expanding and changing your offerings and fine-tuning yourself in the face of ever-changing public tastes and market conditions. New products and new business opportunities always arise in the tiny cracks of the mainstream market. Spin-offs are the best way to capitalize on these niche opportunities and respond quickly.

The use of “ditto” is increasing not only in confessions of love, but also in the process of purchasing goods and services. In fact, purchasing is a sophisticated process that requires very complex decisions. First, the “recognition of the problem” of what to purchase is followed by the “information search,” which involves all the cognitive functions of exposure, attention, perception, memory, learning, and attitude formation. Until a purchase is made, a rigorous “alternative evaluation” is conducted on the selected candidates.

Why should we pay attention to this liquidpolitan concept? Firstly, it’s essential because cities need to be adaptable to accommodate diverse lifestyles. Embracing regional diversity fosters societal creativity. In a world where industries are transitioning to the knowledge sector, the cultural capital that can offer fresh perspectives holds immense value. This is why numerous startups and IT companies worldwide place great importance on urban diversity.

In the past, care primarily revolved around family members or those in close proximity providing support to individuals struggling with independent living, often due to health or age-related issues. Today, the concept of care has undergone a profound transformation. It is no longer limited to those with disabilities or specific needs, and caregivers need not be exclusively family members. Care is becoming increasingly inclusive and expansive in both social and technological dimensions, extending far beyond traditional family boundaries. This shift marks a significant change in how we perceive and practice caregiving.

Caring is increasingly being recognized for its economic value. Caring is becoming the foundation that protects everyone and enables a better life in our slowing economy, contributing as a crucial pillar to the economic cycle, driving the force of new economic growth, which can reflect on GDP. The economic value generated by care is clear.
