The elevator

For most city-dwellers, the elevator is an unremarkable machine that inspires none of the passion or interest that Americans afford trains, jets, and even bicycles. Wilk is a member of a small group of elevator experts who consider this a travesty. Without the elevator, they point out, there could be no downtown skyscrapers or residential high-rises, and city life as we know it would be impossible. In that sense, they argue, the elevator’s role in American history has been no less profound or transformative than that of the automobile. In fact, according to Wilk, the automobile and the elevator have been locked in a “secret war” for over a century, with cars making it possible for people to spread horizontally, encouraging sprawl and suburbia, and elevators pushing them toward life in dense clusters of towering vertical columns.
 

As the world's populations grows and congregates towards cities, we have to build upward towards the skies, so perhaps it's high time we give the elevator its due.

I liked this bit about how the elevator turned the top floor of buildings from the least to the most desirable level.

The arrival of the elevator upended more than urban planning: It changed the hierarchy of buildings on the inside as well. Higher floors had once been distant, scrubby spaces occupied by maids and the kind of low-rent tenants who could be expected to climb six flights of stairs. The more important people climbed at most one or two flights, which gave brownstone-style homes, for instance, their high-ceilinged parlor floors. While the arrival of elevators didn’t change this right away—the top floor of Henry Hyde’s building was occupied by the in-house janitor—the upper reaches of buildings eventually became desirable. The elevator ushered in the end of the garret and the beginning of the penthouse, as lawyers and businessmen came to appreciate the advantages of having beautiful, bird’s-eye views and respite from the loud noises of the street. Hotel owners, meanwhile, started turning their top floor rooms into their nicest ones. They could even rent out their roofs for garden parties where guests could survey the glittering new city, all without doing a bit of work to get there.
 

And I wasn't expecting a discussion of serendipity and elevator systems.

For elevator fans like Bernard, Wilk, Gray, and Carrajat, this mixing of worlds is one of the main things that makes elevators so important. And the more opportunities modern life gives us to separate ourselves from others—by getting into our cars and escaping into our suburban homes, by hiding in our cubicles and burying our heads in our social networks—the more the elevator matters as a place that squeezes us together for a moment and forces us to grapple with one another’s existence.

Sadly, there is cause to worry about the future of these moments. The next big leap in elevator technology, already active in large new office towers, is something called “destination dispatch,” which groups people who are going to similar floors together in order to get them where they’re going more quickly. Such a system, Wilk points out, is more efficient in terms of both time and energy, but it also makes it so that people who work on far-flung floors are less likely ever to run into each other. More specifically, it may reduce the chance that someone high up in a company’s hierarchy would share an elevator ride with someone who works down below. Serendipity, in this scenario, begins to recede.

The anti-social network

Cloak is a new mobile app that “scrapes Instagram and Foursquare to let you know where all your friends, "friends," and nonfriends are at all times so you never have to run into that special someone.”

Funny, but I suspect the people who have enough friends on those services to make this app useful at all might be the exact types of people who would love random social encounters.

I suppose if no one wants to use the app that way they could use it as an efficient stalking facilitator: a built in pivot.

The automatic corporation?

The intermediate step to a fully automated corporation is one where tasks requiring humans are performed not by employees but are broken into micro-tasks and fulfilled by crowdsourcing (using, for example, services like Mechanical Turk).

Corporations do not scale, and eventually die. That’s because they scale sub-linearly. Their productivity metrics scale by an exponent of ⅘ on the number of employees.

I hypothesize that the management overhead which makes corporations grow sub-linearly is due to the limited information processing capability of individual humans. People at the top do not have local on-the-ground information: how are individual products performing, what are customers’ complaints etc. And the rank-and-file folks on the ground do not have the relevant high-level information: how does what I’m doing translate to the value that the corporation as a whole seeks to maximize? In fact, the the flow of value and information is so complex that employees have pretty much given up on determining that relationship, and know of it only at a macro P&L-center level.

An algorithm will have no such problems with acting on both global as well as fine-grained local information. In fact, I suspect that the more information it gets to act on, the better decisions it will make, making automatic corporations grow super-linearly.
 

More here, all fascinating, on the concept of an automatic corporation.

When the idea of two-pizza teams was first proposed at Amazon, it was an attempt at accomplishing two thing simultaneously. On the one hand, keeping teams small was an attempt at giving them autonomy in figuring out what strategy and projects to pursue. On the other hand, since each team had to optimize on a fitness function agreed upon with senior management, it was a model for scaling Jeff Bezos and his senior management team's ability to coordinate activities across the company. If you have a limited number of people you trust to choose the fitness functions, that's still a bottleneck.

The idea of an automatic corporation would replace the humans in both the fitness function and project selection process with software which scales infinitely where humans cannot.

This may sound far-fetched, but the author Vivek Haldar notes it already exists in some forms today.

A limited version of what I’m describing already exists. High-frequency trading firms are already pure software, mostly beyond human control or comprehension. The flash crash of 2010 demonstrated this. Companies that are centered around logistics, like FedEx or Walmart, can be already thought of as complex software entities where human worker bees carry out the machine’s instructions.

This happens naturally, because over time more and more of the business logic of a company becomes encoded in software. Humans still have some control (or so they think) but mostly what they’re doing is supplying parameters to the computation. A modern corporation is so complex that it does not fit in the brain of a single person (or a small number of persons). Software carries the slack.

Free-dimensional cinematography

We saw a glimpse of this with Bullet Time in the Matrix movies and with Microsoft's Photosynth, but now a company called Replay Technologies has come up with the next evolution in what they call Free Dimensional Video.

Our technology works by capturing reality not as just a two-dimensional representation, but as a true three-dimensional scene, comprised of three-dimensional “pixels” that faithfully represent the fine details of the scene. This information is stored as a freeD™ database, which can then be tapped to produce (render) any desired viewing angle from the detailed information.

This enables a far superior way of capturing reality, which allows breaking free from the constraints of where a physical camera with a particular lens had been placed, allowing a freedom of viewing which has endless possibilities.
 

Essentially, you can choose any camera angle in post and the software can recreate it even if there was no camera shooting from that vantage point.

You can see an example of this in the tennis replays in the video below.

Amazing, and also refreshing, for once, to see a video technology debut in sports broadcast coverage instead of pornography.
