Marc Andreessen Excited About Payday Loans



Liberty Street Economics
Except for the ten to twelve million people who use them every year, just about everybody hates payday loans. .... their “unconscionable” and “spiraling” fees and their “targeting” of minorities ..... the typical brick-and-mortar payday lender charges $15 per $100 borrowed per two weeks, implying an annual interest rate of 391 percent! ...... payday lending is very competitive ......

payday lenders outnumber Starbucks

as if they—payday lenders, not Starbucks—were a plague upon the land ..... each additional payday firm per 1,000 residents in a given Zip code was associated with a $4 decline in fees (compared with a mean finance charge of about $55). ...... fixed operating costs and

loan loss rates do justify a large part of the high APRs charged

.” ...... a 36 percent cap eliminates payday loans altogether. ..... payday lenders tend to locate in lower income, minority communities .....

contrary to tenets of classical economists, not all people always act in their own best interest

; they can make systematic mistakes (“cognitive errors”) that lower their own welfare. If chronic rollovers reflect behavioral problems, capping rollovers would benefit borrowers prone to such problems.

Gene Editing Is Now Cheap and Easy—and No One Is Prepared for the Consequences
Scientists — and countries — with less noble intentions could again try to build a race of superhumans...... The DNA of every single organism — every plant, every animal, every bacterium — is now fair game for genetic manipulation. We are entering an age of backyard synthetic biology that should worry everybody. And it is coming about because of CRISPRs: clustered regularly interspaced short palindromic repeats....... CRISPRs use an RNA molecule as a guide to the DNA target. To set up a CRISPR editing capability, a lab only needs to order an RNA fragment (costing about $10) and purchase off-the-shelf chemicals and enzymes for $30 or less........... Because CRISPR is cheap and easy to use, it has both revolutionized and democratized genetic research. Hundreds, if not thousands, of labs are now experimenting with CRISPR-based editing projects...... changing the human germ line is incredibly risky without much better knowledge of how our DNA actually works...... until recently, scientists thought that much of our genetic material was useless and served no purpose. They called it “junk” DNA...... research is emerging showing that junk DNA plays a key role in regulating genetic expression .....

What if a well-intentioned researcher develops a cure for one of these diseases and shares it with thousands of sufferers before realizing that the cure is far worse than the disease and that the side effects are painful — or even deadly — and easily spread from person to person?

..... in the hands of evil biohackers, these powerful and simple tools are a cause for alarm.

A smart biohacker could alter the influenza genome, for example, to make it more potent, setting off an epidemic that kills hundreds of millions of people.

Though a nuclear weapon can cause tremendous long-lasting damage, the ultimate biological doomsday machine is bacteria, because they can spread so quickly and quietly........ No one is prepared for an era when editing DNA is as easy as editing a Microsoft Word document. The government does not have any regulations on editing human DNA. The ethical concerns have not been fleshed out. There is no centralized risk-management inventory, listing which labs are doing what with CRISPR. It’s all rather terrifying...... the stakes in the case of CRISPR are so high that I believe a blanket moratorium is the only course..... such a moratorium could be as effective as the global moratorium on the cloning of humans has been: at the least, scientists such as those who engineered the human embryos in China would become international pariahs rather than being celebrated for publishing papers in prestigious publications.

Cults: Go Outside












JP Rangaswami Comes To "America," England Actually

“I’d never ever left the Indian subcontinent until November 1980, a few weeks after my 23rd birthday…….. I’d never seen trees without leaves, nor a sky that stayed grey all day, without the faintest smidgen of sun. I’d never considered the possibility of walking down a street with no one else in sight in what passed for broad daylight…”

There Is Bollywood And Then There's Sports

What Bollywood is in India, sports is in America. Because Hollywood, big as it is, is not in America what Bollywood is in India.

How You Watch Sports Is About to Change Forever With Virtual Reality
We live in an era of unprecedented global interest in live sports. .... The Summer Olympics holds the highest estimated total viewership, with almost 5 billion people tuning in at some point—approximately 70% of the world’s population.

The entire sports market is worth $700 billion per year, or 1% of global GDP.

...... Sport has a unique, almost unparalleled power to permeate boundaries and bring people together. ..... Yet, the viewing choices for fans are essentially binary: to watch sporting events on TV, or go to a stadium and watch the game live. The former lacks the energy of a live event, while the latter can be expensive and, for most games, is too far away to attend. ..... an exciting new alternative emerging. Virtual reality offers fans the best of both worlds — delivering the electricity of a live game at home (or wherever they are) — and a growing number of new entrants are working to make VR the next big thing in sports. ....... The San Francisco 49ers’ Levi’s Stadium boasts WIFI thirty times faster than any other stadium. The soon-to-be-opened Sacramento Kings Arena promises to be at the cutting-edge of sports experiences. ...... The Pacquaio v Mayweather boxing fight sold out in minutes, with tickets changing hands for upwards of $13,000. ...... VR levels the field, enabling the masses to experience what only a minority might otherwise experience. For live sports broadcasters, virtual reality offers the holy grail of sports fan engagement and monetization —

to be able sell the same seat infinite times.

.
Broadly, these break down into three categories:

  • Stitched 180- and 360-degree film companies using an array of high resolution, often 4K cameras to give an immersive visual experience, coupled by a layered audio experience. Examples of such companies include Jaunt, Next VR, 3D-4U.
  • Player training and performance improvement technology, which enables elite players to run plays repeatedly, improving their knowledge, understanding and execution of those plays. Examples include EON Sports, SIDEKIQ and STRIVR.
  • Immersive social networking for VR, focused around embedded filmed content. Examples include AltspaceVR and LiveLike.
We are not seeking to build a better camera; we are building a new medium. We believe people go to stadiums for more than just the view; they go for the atmosphere, the social interaction, the electricity, the sense of being there. .....

Our mission is to recreate the magic of live events for people around the world.

........ Fans can pick any viewing position, move around and talk to other fans. ..... Primary limitations include the accuracy and depth of 3D data (as gathered by cameras or sensors) and the quality of the virtual reconstruction of the game being tracked (which in turn depends on both high-quality graphical rendering and clever AI). ..... ever improving cameras and methodologies) as well as technological leaps being made in graphics. Virtual experiences are becoming photo-real. The line between filmed and virtual broadcast is narrowing. ...... the recent Jurassic World movie, which features largely CGI landscapes .... A fan can pick any seat in the stadium, but can also experience the game from new perspectives — such as on the field, or watching from the viewpoint of a particular player. They can even float above the field and watch from viewing positions that are very difficult to capture using cameras...... Emotions are difficult to capture using facial tracking. There is a small latency when rendering the event (roughly six seconds). There are technical challenges in dealing with multiple concurrent conversations between fans. ..... We believe the future of live sport viewing will be a combination of actual footage and virtual reconstruction, and that our approach provides that real sense of being there at the game.
I think the idea of recreating "the magic of live events for people around the world" is an exciting proposition.

What if a stadium were to be built catering primarily to the VR experience? Trying to add the VR experience to existing stadiums is the second best option. The best option is where you put the VR experience at the center of it all.

This has use for many things other than live sports. This has use for MOOCs, for example, Massively Open Online Courses. Because, so far, social has been the hard part. How do you do social online? This could be put to use for political gatherings and protests. Egypt might have had a different outcome if a global audience had participated in Tahrir Square.

Done right VR is a richer experience than getting a seat at the stadium. I think you could use this VR thing for extended family gatherings with disastrous effects.

Have you figured out that nausea thing, though?
 
“One day Amitabh (Bachchan) came to me with a box full of sweets. When I enquired about the occasion, he said his daughter had delivered a baby and that he had become a ‘nana’. I jokingly remarked,’it took you so long to become a Nana. Look at me. I am Nana since my birth,” laughed Nana Patekar.
