They can enjoy tech because people see tech improving every aspect of their lives. Nowhere in the the world have people ever seen the rate of technological progress that people in China have. Imagine going from having practically no electronics, to everyone having a cellphone, self driving cars, high speed rail across the whole country, drone delivery, and so on. Naturally, people who've seen technology dramatically improve every aspect of their lives would be optimistic that further technological progress will bring even better life.

Meanwhile, in the west, the standard of living has been eroding for the majority of the population. Technological progress is associated with layoffs, loss of agency at the workplace, and diminishing life prospects. So, it's no surprise that there is growing opposition to AI.
