What does the medium retrieve that had been made obsolete earlier? REVERSES . . . What does the medium reverse or flip into when pushed to extremes? – McLuhan, “Laws of Media” Questions that can be asked of any media What are the side effects of the media on people and society? Especially, when a new medium (M1) appears, it would obsolesces some existing medium (M2) that has obsolesced some other medium (M3), so that M3 would be retrieved by M1, as M2 is now becoming obsolete Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.8/48

of the Internet Write a bulleted list of what the Internet “enhances”, makes “obsolete”, “retrieves” and what it “reverses” into (2) Based on the tetrad you drew, briefly describe how the Internet affects finance Please be concise Deadline and how to submit October 17, 2023 at 17:59 JST From Moodle (mandatory) Optionally, you can also post to #assignments channel at Discord So that people can comment on your reports and start discussions more easily Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.12/48
Measures . . . how to improve the class 23 out of 26 students submitted (as of Thursday afternoon; better late than never) If you don’t see your listed items in the big aggregated tetrad we will see shortly although you thought they were original, did you by any chance submit using image (or PDF/PPT) instead of text so that they cannot be copied and pasted easily? (Just text, please) At Discord, too, please consider sharing by plain-text, as sharing by PDF/PPT means that we have to download your reports and manage files Effects on finance may be a little too conventional (albeit they are good) Considering effects in terms of ENH/OBS/RET/REV is nice There is something there that can be explored more deeply, especially in RET and REV But normally, what everyone knows is 20 years behind (Drucker, 1990) RET and REV seemed difficult to think about (you did pretty good on RET, though) RET in this case : what was made “obsolete” primarily by TV, printing or physical space REV in this case : similar effects as those of TV, printing or physical space Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.13/48

traditional currency ⇒ Money functions to solve the challenge of “double coincidence of wants” So, if we can solve the double coincidence of wants in a different way, then we do not need the money Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.16/48
⇒ That is interesting Does this mean that they “have to” or “necessarily” profit from obscure sources? Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.17/48

internet access ⇒ These are important problems But why do you think the elderly are so poor at the Internet? They can book and record TV programs on video “First mile” problem is being tackled Let us not forget to value the user’s perspective Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.19/48
time focusing on the philosophical side of the matter instead of the technical/info Question on “money” itself, would be a good addition to what we have discussed so far ⇒ Perhaps we will think about it throughout the semester Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.20/48
banking I’m eager to learn how to apply Fintech in the industry, stay current with trends, and develop essential skills ⇒ You also mentioned “De-banking” If banks were to disappear, it would be the ultimate de-banking Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.21/48
materials are pretty new to me yet very inspiring, particularly the concept of A- and X-thinker (an eye-opening one!) I’m interested to know more about how the new technology will transform financial businesses in the next 5-10 years Since the financial sector can influence people’s and businesses’ decision-making, I think it will play a pivotal role in shaping the future world Will human decisions (financial or otherwise) be influenced or directed by AI without us even knowing that? ⇒ Our decisions may already be unknowingly influenced by something Through all sorts of media We also want to be sensitive to how AI and the people behind it are becoming increasingly influential Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.22/48
the Internet on finance? Let’s discuss in small groups First, look at the tetrad you made collectively, see if blue, black and gray classification is right and if there are more effects of the Internet Then discuss side effects of the Internet to finance It will help to look primarily at RET (retrieval) and REV (reversal) Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.23/48

base Put everything in a USB flash drive, put everything on the web “Put anything on it” is the whole idea of USB (Universal Serial Bus) to begin with Do you know what bus is? Improvement of transmission quality → No degradation of information Degradation occurs during sampling and quantization, but does not occur after that Concealment or proof of communication → Encryption or digital signature Public key cryptography (we will have a chance to take a deeper look at it in later class) More efficient transmission → Packet communication, compression One single physical communication medium shared by multiple uses at the same time Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.26/48

Keio Univ. Two among the best private universities in Japan These two universities are known for their rivalry and matches in baseball and other sports known as “ ” (first characters of Waseda, Keio and match), although Keio students would often call it “ ” ;) For undergraduates, classes may have to be cancelled for students to go cheer on the baseball team Story The head of the Keio cheerleading squad sends a letter of challenge in the form of a traditional scroll to the head of Waseda’s cheerleading squad It is a very long scroll that has to be untied from Keio’s Mita campus, slipped into Mita Station on the Mita Line, and then slipped out from Waseda Station on the Tozai Line to reach the Waseda campus so that the head of Waseda’s cheerleading squad can read it This is a metaphor of stream communication over the Internet as we do it via Zoom at the class Two ways TCP (Transmission Control Protocol) . . . Don’t miss reading every word of it (e.g. browsing a web page) UDP (User Datagram Protocol) . . . Well, it’s a long scroll, and it’s okay if it’s missing parts (e.g. Zoom) Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.45/48
way, inside the entrance of Mita Station, there is a photocopier, which copies just part of the scroll at a time, and students pass through the ticket gate with one fragment each in their hand Each fragment is sequentially numbered from the top of the scroll Students are not familiar with the railway network, and when they ask the station staff how to get to Waseda, they are told to go to Otemachi, so they do Students ask again at Otemachi Station (router), and are told to change to the Tozai Line When they arrive at Waseda Station, a student operates a scanner/printer before the exit, scanning the fragments in numerical order and outputting a long scroll on the printer, and students pull it to the Waseda campus Now, some students may get lost on the way What would you do? Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.46/48
TCP Students pick up their receipts (with fragment #) at Waseda Station and take them back to Mita Station At Mita Station, if a receipt is not returned, it is assumed that the fragment was not delivered, and another student is sent out with the fragment UDP Why do we care if some students get lost? (They are grown up, and we are certain that they will make it to their home) Lecture 3 : Internet Technology and Governance (1) — FinTech — Financial Innovation and the Internet 2023 Fall — 2022-10-20 – p.47/48
