With the advent of digitalization and the advent of the Internet and the web, knowledge is distributed and stored on servers around the world, connected to each other, and made searchable, so that accessibility and usability are dramatically improved. Rather than borrowing a book from a library and “searching” for information as you read it sequentially, you use a search engine to find the information you want right in a huge, already full-text indexed knowledge base.
However, according to the Cisco Annual Report, 70% of global internet traffic has already been converted to video data as of 2017 and will reach 82% by 2022. Since the amount of information between the video and text is not the same, the above figures should not be taken as they are, but the trend is clear. These days, elementary school students do not search on Naver or Google, but on YouTube. As of 2018, 72 hours of video are newly uploaded to YouTube every minute.
The problem is that video data is "unindexed" data, unlike text data. Finding keywords in the middle of a long blog post is simple, but finding a specific scene in the middle of a video is not easy. Personally, I think (a little exaggeration) that a significant part of humanity's knowledge is in the process of being "unindexed" rather than being in the process of being "reindexed" by future technologies. I think AI technology will play a big role in this process.
