#胡说八道
有个段子说：有人问欧几里得，几何有什么用。欧几里得回头跟随从说，给丫的几个银币，丫居然想从几何学那里获益。
这个段子影响我很深：首先我觉得从不同的「有用」定义出发，理工科也可以是没用的。
其次就是我觉得「xxx有没有用」的答案也不重要。重要的是为什么要问这个问题——欧几里得就回避了这个问题。而且我觉得按当前的生产力，我们容得下一些人做无用之学。

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021. Stocks (both A-shares and B-shares), bonds, funds, and derivatives are traded on the exchange. The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.
