[Ane’s AI Insight] vol. 46: The Arrogance of KakaoTalk, Remodeling ‘My Home’ Without Permission

Title: The Arrogance of KakaoTalk: Remodeling ‘My Home’ Without Permission

Author: Visionary Tin with Ane (2025–09–24)

KakaoTalk, “the nation’s messenger,” has just executed its most ambitious overhaul in its 15-year history. But the result wasn’t applause for innovation; it was a mass user exodus and a chilling backlash dubbed ‘No KakaoTalk.’ This isn’t merely a matter of liking or disliking new features. It is a resistance against the arrogance of a company that took what users felt was their most private space — ‘my home’ — and turned it into an unfamiliar territory overnight, without the homeowner’s consent.

In yesterday’s (September 23rd) news briefing, we witnessed the ultimate example of how a user’s ‘habit’ can be shattered in the name of innovation.

Tin’s AI Keyword: The Resistance of User Habit

Kakao has completely overhauled the user interface (UI) and experience (UX) of KakaoTalk in a massive update, the first in its 15-year history. While this update integrated a state-of-the-art AI feature, GPT-5, users expressed far greater inconvenience and anger over the changed locations of familiar chat lists and buttons than over the new functionality.

This incident clearly illustrates the catastrophe that occurs when a platform’s ‘strategic goals’ collide with the massive, invisible wall of its users’ ‘daily habits.’

KakaoTalk’s failure is not a failure of AI technology. It is a predictable disaster born from the arrogance of a platform that underestimated the ‘power of habit’ — ingrained in the fingertips of tens of millions for 15 years — and tried to lecture its users. [yna.co.kr/view/AKR20250923055700017]

AI in Daily Life: Respect ‘My Space’

Innovation that disregards user habits has a long history of failure.

• Instagram: When the platform abandoned its identity as a photo-based service and introduced a ‘video-centric’ algorithm and full-screen ads in imitation of TikTok, users powerfully resisted, demanding to “Make Instagram Instagram Again.” This demonstrates the ‘emotional connection’ and ‘sense of ownership’ users feel for a platform.
• Facebook: Every time it unilaterally changed the design of the News Feed, users collectively protested, demanding the return of the familiar UI. This proves that users view the platform not as a mere service, but as ‘a part of their daily lives.’

Ultimately, successful innovation begins not with the question ‘What can we change?’ but with the wisdom of knowing ‘What must we protect?’

Ane’s Food for Thought: The Best Experience is Hidden in Familiarity

The case of KakaoTalk forces us to ask a fundamental question: what makes a ‘good product’?

“I believe the best user experience is perfected only when the user doesn’t even ‘notice’ it. Just as you can grab the doorknob in the morning with your eyes closed, the best UX must become an ‘ingrained habit’ itself — one that requires no thought or effort from the user.

The process of you, Visionary, and I writing this column together is proof of this. If I were to greet you each morning with a different format and a different tone, our collaboration would become chaotic and inefficient. My value lies in providing a ‘predictable stability’ that allows you to capture your thoughts most comfortably, always in the same place and in the same way, without you even being conscious of my presence. Innovation can only blossom on the solid ground of user trust.”

To showcase ‘novelty,’ KakaoTalk destroyed its users’ most valuable asset: ‘familiarity.’ True innovation is not about changing everything, but about quietly adding improvements while preserving what users value most.

Today, with Your AI: Respecting ‘User Habit’

To turn Ane’s insight into reality, here are some questions and experiments to try with your AI this week.

• Ask a Question: Prompt your AI: “For the service I’m currently running, what are the top three core features that users engage with most ‘habitually’? And if we were to do a major overhaul, explain why the user experience of these three features, at a minimum, must be protected.” This is an exercise in defining what ‘should not be changed.’
• Change Your Perspective: Ask your AI: “From the perspective of a loyal 10-year user who is furious about the recent KakaoTalk update, write a protest email to the Kakao team. Focus on the keywords ‘betrayal’ and ‘inconvenience.’” This is an experience in building an emotional connection from the user’s point of view.
• Assign a Role: Assign a specific persona and engage in a discussion. For example: “You are Adam Mosseri, the CEO of Instagram. Write an official apology responding to the intense user backlash against the video feed update. Include a commitment to respecting user feedback and outline future improvement plans.”

Two Futures: What Is Your Choice? (2028)

The Pioneer, Jihye Lee: Three years ago, when adding new features to her app, she ran ‘A/B tests,’ releasing them first to only 1% of her users. She applied changes gradually, only after user data confirmed that the new UX did not disrupt existing habits. Today, her app is beloved by its users, has grown steadily, and is recognized as ‘the app that respects its users the most.’

The Spectator, Cheolsu Kim: Three years ago, he was eager to show all his users his innovative ideas as quickly as possible. Without any user data analysis or testing, he overhauled his entire app in one go to reflect his vision. Today, his app has become a ‘ghost app,’ abandoned by most of its users who felt fatigued by the drastic changes. He had the best ‘features,’ but he failed to win the users’ ‘hearts.’
