In the era of post-Corona, all products and services need the marketing of "high-touch and high-concept". There is always a new story if technology develops at a rapid pace. On the one hand, there is a concern that technology will have a negative effect on human mindset. I know that people in modern society have a common syndrome in their lives. Today, people are experiencing the "shock of technology" that they cannot catch up with. Also, we can deal with things only when we take advantage of mobile technology. I want to call this "tech-addiction syndrome". What are "high-touch and high-concept'? This is just related to "digital marketing". I don't think these are part of high-tech advancement. Nevertheless, high-touch and high-concept are just a psychological approach. In conclusion, everyone has to learn technologies, but we have to explore the human psyche. Finally, in the end, humanity will be conquered by technology, but people will remain as "legacy".
