But the difficulty has not disappeared, it has only moved somewhere else. It has shifted from "can you build it" to "can your product stay alive after launch".Mon, 24 Aug 2026 00:00:00 GMThttps://www.nguyentantoan.com/en/blog-post/bernie-vs-claude-and-the-illusion-of-an-objective-ai/https://www.nguyentantoan.com/en/blog-post/bernie-vs-claude-and-the-illusion-of-an-objective-ai/Are you getting an objective answer from AI?

As the technology starts solving problems as complex as the ones people handle, the experience of interacting with it has to change too. If the experience can't keep up with the power of the technology, users will walk away, no matter how smart the AI is.Sat, 14 Feb 2026 00:00:00 GMThttps://www.nguyentantoan.com/en/blog-post/ai-native-designer-design-in-the-ai-era/https://www.nguyentantoan.com/en/blog-post/ai-native-designer-design-in-the-ai-era/AI does not replace the design thinking of people who build products.
