I bought a book named "Marginal Cost Zero Society", which is full of interesting keywords like IoT, Sharing Economy and Marginal Cost Zero.

I bought a book via SNS on impulse. I think this is the first time for me to buy a book in this way.

The trigger was a tweet by Mr. Tabata.

The title has interesting keywords like IoT and Sharing Economy, and also has a economic term of "marginal cost", which I had studied before. But rather than these interesting words, I was thrilled by his comment "It's a pity that this book lacks a catchy label...".

I bought it very soon because the summary indicated that this book has something in common with Mr. Motani's book "Satoyama Capitalism". Long time no buy via Amazon. I ordered it on Sunday, and it was delivered on Tuesday, Very quick, eh?

I've just started reading it, and I began to feel that Marginal Cost Zero Economy, which is the final goal of capitalism, has very similar points with economies of rural areas. Products and services are offered for free in both economies because the cost is zero at the former economy and people share with each other at the latter economy. The reasons are different, but I guess I will find a lot to learn.

I will write down what I learnt from the book after I read it a bit more.
