While getting on the long distance bus, I tried to talk to a young man sitting next to me. In the past, I rode these kinds of bus, but I never sat next to young men. This time, the bus was not at night but daytime. So even though talking in the bus disturbs other passengers, I and he kept chatting as time allowed.
He works in TV from this year, and gets the induction course. He was a researcher of optic fiber cable, so he taught me how the Internet works. The fibers physically connect to other countries usually under the ground or sometimes in the sea. If the fiber was cut off, all the information cannot go through meaning that citizens must feel panicked because of not getting any information from their smartphones. It's worse than not getting any import stuff in these days I suppose.
As I learn from him, I realize that I don't understand how the Internet or Wi-Fi works even though I use them every day. It's kind of scary without knowing the mechanism. As an end user of the product, better be smart enough at least how to protect my personal information. Sometimes I receive emails saying that someone in another country attempts to log in with my account (Gmail). Once, I experienced being hacked my Facebook account sending meaningless messages to all my Facebook friends. Now, people are willing to share their pictures and videos, but it gets weird in fact. Posting on Facebook is not exactly the same as sending pictures to your friends. I am also a user of Facebook, so it's not for saying that it's a bad thing, however, we should be aware of the role of Facebook. Understanding how sharing personal information makes the company profits is the key. Ads. The system of facial recognition is fucking awesome but terrible at the same time.
He taught me about the profit of Shinkansen (the bullet train). Each shinkansen has thirteen train cars. When all seats are taken just one train car, it fills the running cost. All the fee of the other twelve train cars directly profit. He suggests me to invent a system like rail transport that many people use everyday. One of the examples is Watson invented by IBM. I really respect the engineers who contributed to invent the AI. They are changing not only the rules of business but also the way of working.
Instead of learning a lot from him, I gave him a cup of milk pudding that a farmer produces and I explained why I bought the product. I love to support the business that comes alive in local areas. As a producer of the primary sector of industry such as farmers or fishermen, it's inevitable to develop a unique approach to sell their own products to the markets or the restaurants. Dead end if you just ask others to do the role instead.
