Human writer or AI? A detection model being developed at Stanford


The Human Centered Artificial Intelligence program at Stanford University reports that scholars there have built a detection program that "...can determine with up to 95% accuracy whether a large language model wrote that essay or social media post."  For more information on their efforts, use this link to the news release.

After a somewhat long hiatus in posting to my blog, I'm planning to follow developments relating to the public release of chatGPT and competing programs soon to be released by Microsoft, Facebook (Meta) and others.  This Spring semester I'm teaching both an undergraduate course on digital networks and innovation and a graduate seminar on networked communication technologies, so the development and spread of generative natural language programs is highly relevant in both classes.

More on the decline of Internet Cafes (aka PC Bangs)

 The Chosun Ilbo English edition caught my eye with the headline "Internet Cafes Vanish."  In fact, they have not vanished, but their use has declined dramatically during the Covid and post-Covid era.  For further background and detail on the Internet Cafe (AKA PC Bang) phenomenon in South Korea, search this blog ( a search on "PC Bang" yeilds this result).

Korea to spend $144 million on digitalization of R&D

 As reported by The Korea Herald, "South Korea will spend 200 billion won ($144 million) on digital integration strategy projects over the next five years to shorten the time researchers take to solve complex problem surrounding new technologies by decades, the Ministry of Science said Tuesday."  Furthermore, the announcement indicated that "... the government will use the financial support for projects that integrate artificial intelligence, digital twin and big data into developing diagnoses of diseases such as intractable cancer and dementia, nine new materials and prediction models of changes in space."

Revisiting the Rise and Fall of PC Bangs (a.k.a. Internet Cafes) in Korea


As readers of this blog will know, I've long been following the introduction, growth and decline of PC Bangs (literally PC Rooms), also known as Internet Cafes, in South Korea.   A search for "PC Bang" will locate a number of my earlier posts and provide some background on the main factors accounting for the emergence of PC Bangs and their eventual decline.  The graphic presented here charts the number of PC Bangs in Korea from their introduction in 1998 through 2020, as estimated by the Korea Creative Content Agency in their annual white papers on Korean games. (click on the graphic to see a full size version with the numbers legible at the top of bars)  Several patterns in this graphic are noteworthy.

First, the explosive growth in the number of PC Bangs from 1998 to 2000 coincided with the rapid growth of broadband internet services, led by Thrunet's cable modem service, followed shortly thereafter by Hanaro Telecom's entry into the market with DSL service.

Second, the decline in number of PC Bangs starting in 20010 coincided with the arrival of Apple's iPhone to the Korean market.  This arrival came two years after its introduction in the U.S. and after it had become popular in about 80 other countries.   2009 was also the year that Samsung and LG began manufacturing Android smart phones.  The improving technical capabilities of Android and Apple smart phones contributed to the growth of mobile games, at the expense of those played in PC Bangs or Arcades.

Third, from 2016 to 2019 there was a slight resurgence in the number of PC Bangs as Internet Cafe franchises entered the market and owners adapted to government regulations about the sale of food in them.

Death of Internet Explorer goes viral


Readers of this blog will know that I've long been interested in Korea's heavy dependence on Microsoft's Internet Explorer browser, years after Microsoft itself warned against its use (click here for posts on IE and cyber-security).  The tombstone displayed in this photo (click for a full size version) was made by a Korean software engineer and displayed on the roof of his brother's cafe in Gyeongju went viral on the Internet.

The story was covered by CNN (see story here) and other mainstream media, but a review of posts on this blog will provide additional detail.
