Hidden Amazon page drops hints about a ‘Fire TV Cube’

Rumors have been floating around for a few months now of a new device from Amazon that would mash-up the media streaming capabilities of its Fire TV line with the voice assistant abilities of the Echo. After leaked images turned up showing a cube-shaped device that seemed to fit the bill, people started referring to this still as-of-yet unannounced device as the “Fire TV Cube.”

Sure enough: a seemingly official page has been found tucked away on Amazon.com that mentions a Fire TV Cube, and promises “details coming soon.”

As found by AFTVNews, the placeholder splash page offers up little beyond the promise of eventual details. It’s got a big ol’ header that says “What is Fire TV Cube?”, a button to let you sign up for more details and… well, that’s about it.

There’s also a mention of a “Fire TV Cube” on this page, tucked away in Amazon’s account management backend to let folks toggle their subscriptions to any one of the dozens of newsletters/email campaigns that Amazon sends out.

According to the original leaks, the Fire TV Cube would have the speaker, far-field microphones and LED light bar of an Echo and the 4K video-capable guts of a Fire TV, allowing you to hook it up to your TV and have one device doing double the duties.

In other words: While there’s still no official word on when (or if!) this thing will actually ship, it definitely looks like they’re prepping for something behind the scenes.

Facebook and the perils of a personalized choice architecture

The recent Facebook-Cambridge Analytica chaos has ignited a fire of awareness, bringing the risks of today’s data surveillance culture to the forefront of mainstream conversations.

This episode and the many disturbing prospects it has emphasized have forcefully awakened a sleeping giant: people seeking information about their privacy settings and updating their apps permissions, a “Delete Facebook” movement has taken off and the FTC launched an investigation into Facebook, causing Facebook’s stocks to drop. A perfect storm.   

The Facebook-Cambridge Analytica debacle is composed of pretty simple facts: Users allowed Facebook to collect personal information, and Facebook facilitated third-party access to the information. Facebook was authorized to do that pursuant to its terms of service, which users formally agreed to but rarely truly understood. The Cambridge Analytica access was clearly outside the scope of what Facebook, and most of its users, authorized. Still, this story has turned into an iconic illustration of the harms generated by massive data collection.

While it is important to discuss safeguards for minimizing the prospects of unauthorized access, the lack of consent is the wrong target. Consent is essential, but its artificial quality has been long-established. We already know that our consent is, more often than not, meaningless beyond its formal purpose. Are people really raging over Facebook failing to detect the uninvited guest who crashed our personal information feast when we’ve never paid attention to the guest list? Yes, it is annoying. Yes, it is wrong. But it is not why we feel that this time things went too far.

In their 2008 book, “Nudge,” Cass Sunstein and Richard Thaler coined the term “choice architecture.”  The idea is simple and pretty straightforward: the design of the environments in which people make decisions influences their choices. Kids’ happy encounters with candies in the supermarket are not serendipitous: candies are commonly located where children can see and reach them.

Tipping options in restaurants are usually tripled because individuals tend to go with the middle choice, and you must exit through the gift shop because you might be tempted to buy something on your way out. But you probably knew that already because choice architecture has been here since the dawn of humanity and is present in any human interaction, design and structure. The term choice architecture is 10 years old, but choice architecture itself is way older.

The Facebook-Cambridge Analytica mess, together with many preceding indications before it, heralds a new type of choice architecture: personalized, uniquely tailored to your own individual preferences and optimized to influence your decision.

We are no longer in the familiar zone of choice architecture that equally applies to all. It is no longer about general weaknesses in human cognition. It is also not about biases that are endemic to human inferences. It is not about what makes humans human. It is about what makes you yourself.

When the information from various sources coalesces, the different segments of our personality come together to present a comprehensive picture of who we are. Personalized choice architecture is then applied to our datafied curated self to subconsciously nudge us to choose one course of action over another.

The soft spot at which personalized choice architecture hits is that of our most intimate self. It plays on the dwindling line between legitimate persuasion and coercion disguised as voluntary decision. This is where the Facebook-Cambridge Analytica story catches us — in the realization that the right to make autonomous choices, the basic prerogative of any human being, might soon be gone, and we won’t even notice.

Some people are quick to note that Cambridge Analytica did not use the Facebook data in the Trump campaign and many others question the effectiveness of the psychological profiling strategy. However, none of this matters. Personalized choice architecture through microtargeting is on the rise, and Cambridge Analytica is not the first nor the last to make successful use of it.

Jigsaw, for example, a Google -owned think tank, is using similar methods to identify potential ISIS recruits and redirect them to YouTube videos that present a counter-narrative to ISIS propaganda. Facebook itself was accused of targeting at-risk youth in Australia based on their emotional state. The Facebook-Cambridge Analytica story may have been the first high profile-incident to survive numerous news cycles, but many more are sure to come.

We must start thinking about the limits of choice architecture in the age of microtargeting. Like any technology, personalized choice architecture can be used for good and evil: It may identify individuals at risk and lead them to get help. It could motivate us into reading more, exercising more and developing healthy habits. It could increase voter turnout. But when misused or abused, personalized choice architecture can turn into a destructive manipulative force.

Personalized choice architecture can frustrate the entire premise behind democratic elections — that it is we, the people, and not a choice architect, who elect our own representatives. But even outside the democratic process, unconstrained personalized choice architecture can turn our personal autonomy into a myth.

Systematic risks such as those induced by personalized choice architecture would not be solved by people quitting Facebook or dismissing Cambridge-Analytica’s strategies.

Personalized choice architecture calls for systematic solutions that involve a variety of social, economic, technical, legal and ethical considerations. We cannot let individual choice die out in the hands of microtargeting. Personalized choice architecture must not turn into nullification of choice.

‘Avengers: Infinity War’ is an overstuffed adventure with a terrific villain

When I saw the first trailer for Avengers: Infinity War, I was really excited and really worried.

Excited because, holy crap, there were so many characters. Iron Man! Captain America! Thor! Black Panther! Black Widow! The Vision! The Guardians of the Galaxy! And they were all going to be in a movie together!

Worried because, holy crap, there so many characters. How could you squeeze all of them into a single film?

The answer is, with great difficulty. To be fair, Infinity War isn’t the giant mess that it could have been — in fact, it’s a lot of fun. But there’s simply not enough movie to do justice to the enormous cast.

Infinity War

Some of those characters fare better than others. For most of Infinity War, the “cosmic” side of the Marvel Cinematic Universe is well-represented by Thor (Chris Hemsworth) and the Guardians of the Galaxy (Chris Pratt, Zoe Saldana and team), who end up working together. Screenwriters Christopher Markus and Stephen McFeely are more willing to spend time with them, even when they’re not involved in a giant battle, and that pays off with the movie’s funniest moments — as well as scenes with real weight and melancholy.

Meanwhile, Iron Man (Robert Downey Jr.) and Spider-Man (Tom Holland) also get some good jokes in, recapturing the fun of their relationship in Spider-Man: Homecoming.

Everyone else? Well, they’re usually introduced with a nice quip or a bad-ass moment, designed to remind you of how much you liked them in their own movies. But afterwards, they tend to fade into the background, becoming just another moving part in the big action set pieces (and yes, this includes Marvel’s new MVP Black Panther). That’s probably about as good as any filmmaker could do when trying to stuff the entire Marvel Universe into a single movie, but it’s still a little disappointing after the first Avengers film managed to give us five distinct and memorable heroes (sorry, Hawkeye), and it got so much mileage out of throwing those heroes together.

Luckily, the film’s real strength isn’t on the heroic side. Instead, as in Black Panther (and virtually no other Marvel movie), Infinity War‘s most memorable character is actually the villain, Thanos.

Previous films have reduced Thanos to a purple guy who utters a few threatening lines while sitting in his silly looking space throne. In Infinity War, Thanos is at the center of the action. His quest to acquire the super-powered Infinity Stones drives the story, as all of Marvel’s heroes scramble to stop him, giving the film a constant feeling of crisis and leading fairly quickly to spectacular fights on Earth and in space. He even gets to kill off a surprisingly large number of those heroes (though I don’t expect all of those deaths to stick).

Over the course of the film, Thanos emerges as a dangerous and powerful alien who’s absolutely devoted to his mission of destroying half the life in the universe — kind of a weird goal, but as Walter Sobchak once said, at least it’s an ethos. And as portrayed by Josh Brolin (via voice acting and motion capture), he doesn’t come off as a cackling villain. Instead, he’s a weary soldier at the end of a long quest.

I shouldn’t say too much about where that quest leads, but I will note that Infinity War feels very much like the first half of a two-part film, with an ending that sets up the still-untitled Avengers 4 (due May 3, 2019).

I do think Infinity War falls a little short of Marvel’s best movies, like Black Panther and Captain America: The Winter Soldier (which, like Infinity War, was directed by Anthony and Joe Russo). But here’s one simple measure of the film’s success: Despite my reservations, that cliffhanger worked, and I really, really want to know what happens next.

It’s going to be a long wait till 2019.

Vacation rental management service Guesty raises $19.75M

As the vacation rental sector heats up — with Airbnb making even more moves to expand its portfolio of services to include multiple tiers of rentals — there’s going to be more and more of a need for people who manage a large number of properties.

Guesty is one service that aims to do that, and today a filing with the Securities and Exchange Commission notes that it’s raised $19.75 million in a new Series B round of financing. While Airbnb may be the dominant home vacation rental service, there are others like VRBO, and managing those properties across multiple different platforms could require handling all of that information in something more analog like an Excel sheet. It’s a kind of CRM tool for property management, ranging from tracking guest check-ins to the amount of revenue a property owner. Guesty also helps property owners by providing tools to manage operations beyond just the tracking.

Airbnb earlier this year started rolling out more tiers of home categories that are geared toward different kinds of travelers. That included high-end tiers called Airbnb Plus and Beyond by Airbnb. While these new categories potentially offer a more granular set of choices for consumers, it might make managing those properties a little more difficult — especially if it’s across multiple different services like Airbnb and VRBO, or even more analog channels. Tools like Guesty can help owners of multiple different properties (that might span multiple tiers) turn those homes into an actual business.

There are also plenty of platforms that are looking for additional services for people managing multiple properties on vacation rental sites. There are startups like Beyond Pricing, which look to help property managers figure out how to best price their homes. Airbnb has its own pricing algorithms, but there’s clear demand for tools that cross multiple platforms. Guesty was party of Y Combinator’s winter 2014 class, and raised $3 million in May last year.

While Airbnb continues to try to expand into new categories and offer home owners a way to rent out their homes — or for owners of multiple properties to run a side business — it’s not the only approach to vacation rentals. One startup, Selina, is looking to convert existing properties into kinds of campuses that cater to different tiers of travelers, ranging from travelers looking to stay in a hostel to ones that are willing to pay for their own rooms. Selina earlier this month said it raised $95 million. Selina is more of a hotel-ish model as it expands from geography to geography, but it also shows that there’s demand for an experience that can cater to a wide variety of guests.
