Today, I think the world is divided into analogue and digital. In particular, due to the global pandemic, the digitalization of the world is gaining momentum now. Also, polarization is becoming serious. Analogue jobs are declining, while digital jobs are rising. Specifically, digital workers are becoming popular among people. Reportedly, the Yoon's government recently announced that it will nurture up to1 million digital workers from now on. Lately, most jobs are closely related to semi-conductors, AI, IT developing, to name a few. All of them can be called a single word "ICT". Digital workers get paid a lot! Eventually, people of the next generation will have to be a lot more interested in "digital". Digital is probably similar to "drug".
