I think emerging technology has advanced PLN. At the same time, I am curious if online teaching can completely replace offline teaching. In the past year, most students took classes online, whether voluntarily or not. Due to the time zone difference, many teachers post their teaching videos online. In my personal experience, I started out unfamiliar with the system and have come to prefer online classes. Depending on my schedule, I can always learn from the Internet. Compared to offline classes, online classes are convenient and flexible. Software similar to blog is even more known, and bloggers share everything from dressing to academic knowledge . More and more professionals are joining the sharing community. Due to the wide spread of the Internet, emerging technologies will change the traditional teaching profession. I think there will be some faculty members who will lose their jobs. Facing the trend of emerging technology, it is a problem how to arrange the re-employment of career employees.
