Remember: Just because an idea is old doesn't mean it's good.

Knowing whether old ideas are more likely to be good requires understanding whether conditions have changed in important ways.
Horse archery was an amazing method of warfare for over a thousand years...then people invented guns, and suddenly this great idea that had stood the test of time became obsolete.
Then again, when underlying conditions don't change much, tried-and-true approaches are probably better.
"Learning the lessons of history" usually just means assuming ergodicity and stationarity in an informal time-series model...

1/I'm thinking about the end of Apu in the context of the national debates on immigration and diversity.


2/Apu's presence in Springfield represented a basic reality of America in the late 20th and early 21st century: the presence of nonwhite immigrants.

3/As Tomas Jimenez writes in "The Other Side of Assimilation", for my generation, immigrants from India, China, Mexico, and many other countries aren't strange or foreign. On the contrary, they're a

4/But that America I grew up with is fundamentally ephemeral. The kids of immigrants don't retain their parents' culture. They merge into the local culture (and, as Jimenez documents, the local culture changes to reflect their influence).

5/Simpsons character don't change. But real people, and real communities, do. So a character who once represented the diversity that immigrants brought to American towns now represents a stereotype of Indian-Americans as "permanent foreigners".
When Republicans started to believe in racial bloc voting - when they stopped believing that nonwhite people could ever be persuaded to vote Republican - they started to see immigration as an invasion.

This explains why immigration is now at the center of partisan conflict.


Of course, the belief in ethnic bloc voting becomes a self-fulfilling prophecy.

When a slight Dem tilt among Hispanics and Asians caused the GOP to turn against them, Hispanics and Asians shifted more toward the Dems. Etc. etc. A self-reinforcing cycle.

Bush's 2006 amnesty attempt, and the 2013 intra-GOP fight over immigration reform, were two moments when the GOP could have turned back to the approach of Reagan, and courted Hispanics and Asians.

But they decided against this, and...here we are.

What will disrupt this bad equilibrium, and save American politics from being an eternal race war?

Either:
A) More white voters will grow disgusted with the GOP approach and defect, or
B) The GOP will find some non-immigration-related issues to attract more Hispanics and Asians.

As long as both parties see elections in terms of racial bloc voting - where the only way to win is to increase turnout among your own racial blocs or suppress turnout by the other party's racial blocs - American politics will not improve, and the country will decline.

Time for panel #3: Big Tech and regulation!

I will be live-tweeting again, and you can also watch video at either the Twitter or Facebook links below!


Kaissar: Every industry gets regulated when it gets big. The question is what kind of regulation Big Tech will get,and whether the companies will be proactive in shaping it.

Kaissar: More profitable companies have higher returns. Why? Maybe it's a risk factor, because more profit = higher risk of getting regulated.

Bershidskyis showing a diagram of GDPR complaince pop-ups. What a massive ill-conceived bureaucratic mess.

Ritholtz: It's 2018 and we're still talking about Facebook privacy settings?! If you're still giving your personal data to Facebook, you just don't care about privacy!

दधीचि ऋषि को मनाही थी कि वह अश्विनी कुमारों को किसी भी अवस्था में ब्रह्मविद्या का उपदेश नहीं दें। ये आदेश देवराज इन्द्र का था।वह नहीं चाहते थे कि उनके सिंहासन को प्रत्यक्ष या परोक्ष रुप से कोई भी खतरा हो।मगर जब अश्विनी कुमारों ने सहृदय प्रार्थना की तो महर्षि सहर्ष मान गए।


और उन्होनें ब्रह्मविद्या का ज्ञान अश्विनि कुमारों को दे दिया। गुप्तचरों के माध्यम से जब खबर इन्द्रदेव तक पहुंची तो वे क्रोध में खड़ग ले कर गए और महर्षि दधीचि का सर धड़ से अलग कर दिया।मगर अश्विनी कुमार भी कहां चुप बैठने वाले थे।उन्होने तुरंत एक अश्व का सिर महर्षि के धड़ पे...


...प्रत्यारोपित कर उन्हें जीवित रख लिया।उस दिन के पश्चात महर्षि दधीचि अश्वशिरा भी कहलाए जाने लगे।अब आगे सुनिये की किस प्रकार महर्षि दधीचि का सर काटने वाले इन्द्र कैसे अपनी रक्षा हेतु उनके आगे गिड़गिड़ाए ।

एक बार देवराज इन्द्र अपनी सभा में बैठे थे, तो उन्हे खुद पर अभिमान हो आया।


वे सोचने लगे कि हम तीनों लोकों के स्वामी हैं। ब्राह्मण हमें यज्ञ में आहुति देते हैं और हमारी उपासना करते हैं। फिर हम सामान्य ब्राह्मण बृहस्पति से क्यों डरते हैं ?उनके आने पर क्यों खड़े हो जाते हैं?वे तो हमारी जीविका से पलते हैं। देवर्षि बृहस्पति देवताओं के गुरु थे।

अभिमान के कारण ऋषि बृहस्पति के पधारने पर न तो इन्द्र ही खड़े हुए और न ही अन्य देवों को खड़े होने दिया।देवगुरु बृहस्पति इन्द्र का ये कठोर दुर्व्यवहार देख कर चुप चाप वहां से लौट गए।कुछ देर पश्चात जब देवराज का मद उतरा तो उन्हे अपनी गलती का एहसास हुआ।
