特朗普與689

在網上見到有不少本土言論對特朗普的作風大表認同,認為是對左翼人仕的打擊。 我覺得這是十分奇怪的看法 。
 
特朗普由參選開始已經謊話連篇,政策民粹至上。上任後不顧利益衝突,政策閉門造車,用人唯親—最新消息是他從國家安全委員會裏免去三參軍參謀長及國家情報局長,只留下一眾親信—還起用了一個不知所謂的發言人。有沒有覺得這樣似曾相識?這分明就是美版689。
 
在特朗普當選之前我跟我的美國朋友說。我們香港過去五年所經歷的,你們也要經歷。結果特朗普比689更厲害:還不到一星期就已經把美國的政治道德底線推至歷史新低,更不用說美國總統的一個決定就可以讓無數人家破人亡。
 
有人會說特朗普是民選出來的,管治完全合法。這個說法沒錯,不過689的管治也是完全合法,又不見得大家覺得應該乖乖就範。而說到民意支持,美國和香港一樣也是用間選,特朗普和689一樣都沒有大多數市民的支持。689在上任之初,還受不少港人歡迎呢!
 
在今次移民禁令事件中的另一個觀察,是舉世的執法機關基本上都是唯命是從。在上位者的要求,前線人員基本上都會執行。如果說美國人民應該接受特朗普的政令,那香港市民亦都一樣。如果這樣,大量於去年被捕、受迫害的年輕人,又有誰為他們伸張正義?

Pay for the Wall with Tariff

The rumor is that Trump is going to slap a steep tariff on Mexican imports to pay for the border wall. This by itself is not surprising, as it is the only option that could be realistically claimed as making Mexico pay up.

The thing is, it doesn’t make any economic sense.

As anyone with common sense can predict, sellers of Mexican products will certainly shift a significant portion of the tariff to American consumers. Any decent ECON 101 would have taught the logic behind tax burden, and unless Mexico have no alternative use of their productivity, Americans consumers will have to pay a lot.

Some might say buying American would solve the problem. Or does it? Suppose every Americans decide to become true patriots and stop buying Mexican products—most likely out of patriotism to their wallets—such that import from Mexico drops to zero. Guess what? The tariff revenue will be zero. So ironically, the more patriotic Americans are, the more they will be paying for the wall.

This type of nonsense is what makes Trump so dangerous. He doesn’t care about the practicality of his orders and the whole country has no choice but to go along with him.

If Trump can put a gag order on EPA, he probably will try to do the same to BLS in the future. No more unemployment statistics. That would be the easiest way for him to claim credit for creating jobs.

除了AlphaGo,其實還有很多值得留意的人工智能發展。例如現在正在美國進行中的無上限德州撲克大賽,由Carnegie Mellon大學的人工智能對世界上最頂尖的人類選手進行20天的比賽。到目前為止戰況可說是一面倒向電腦一方。
和圍棋不同,德州撲克是一種有隱蔽資訊的遊戲,參賽者並不知道對手以及未派發的牌為何。因此德州撲克相比起圍棋對解決很多現實中的問題意義更大。
Texas Hold’em is a much more interesting game than Go when it comes to real-world artificial intelligence application, since many important real world issues inherently involves imperfect information. 5 days into the game and the human pros are losing badly.

Claudico battles Donger Kim, Jason Les, Bjorn Li, Doug Polk in Brains vs. AI at Rivers Casion, the first time that a computer program has played Heads-up No-limit Texas Hold’em in competition with top human players.
