Speed and digital technology in Korea's fight against COVID-19

I've commented frequently over the years on the importance of speed in digital networks.  Speed can refer to download speeds on mobile or fiber optic networks, processing speed in computers, mobile phones and data centers, and so forth.  Korea today possesses some of the world's fastest digital networks and has built e-government and big data while using these networks.  The speed of networks and data processing here has proven to be a significant advantage for Korea in fighting COVID-19.   The Korea Times, in collaboration with The Korea Foundation, is publishing a five part series on Korea's response to the Covid pandemic.  The latest installment, entitled "Korea's ICT, AI, Biotech shine in virus crisis" makes it clear that fast, state-of-the-art digital technologies are a key enabler of fast contract tracing, public education and related efforts to contain the virus.
