The hand of the market

2021年02月02日 | 英単語
Yuval Noah Harariの "Homo Deus" にはなるほどと思わせる主張が満載です。
Yet mixing godlike technology with myopic politics also has its downside. Lack of vision isn't always a blessing, and not all visions are necessarily bad. In the twentieth century the dystopian Nazi vision did not fall apart spontaneously. It was defeated by the equally grand visions of socialism and liberalism. It is dangerous to trust our future to market forces, because these forces do what's good for the market rather than what's good for humankind or for the world. The hand of the market is blind as well as invisible, and left to its own devices it may fail to do anything at all about the threat of global warming or the dangerous potential of artificial intelligence. We often imagine that democracy and the free market won because they were 'good'. In truth, they won because they improved the global data-processing system.

私はAIはまだまだ人間の足元程度だと思っていましたが、 "Homo Deus" の著者はAIが備えている危険性を予告しています。確かに数十年後には色々と面倒な問題が発生しそうだ。

lucid dream

2021年02月01日 | 英単語
Yuval Noah Harariの "Homo Deus" を読んでいます。
In addition to smelling and paying attention, we have also been losing our ability to dream. Many cultures believed that what people see and do in their dreams is no less important than what they see and do while awake. Hence people actively developed their ability to dream world, which is known as 'lucid dreaming'. Experts in lucid dreaming could move about the dream world at will, and claimed they could even travel to higher planes of existence or meet visitors from othere worlds.

"lucid dream" は "oneiric lucidity" を取り上げた時(11/24/2020)に出てきましたね。
 
辞書の説明を引用します。
・Collins Dictionary: a dream in which the dreamer is aware that he or she is dreaming and can sometimes influence the course of the dream: Then he discovers lucid dreaming, where the brain realises it is in a dream and can learn to control it.
確かに、眠りから覚めているにも関わらず睡眠中に見ていた続きを見ることがあるのですが、それが "lucid dreaming" なのでしょうか?
