John Psathas (*1966): Waiting For The Aeroplane (1988)

Recorded live at the Greek National Gallery, November 10th, 2009, Athens premiere.

John Psathas: Waiting For The Aeroplane

Technology is a progression of new ideas and new platforms gobbling up the one that came before. In the world of computers we went from mainframes to mini computers to PCs. And then came the mobile phone, which, in the form of the smartphone, has dwarfed them all. But what does that to mobile? When you have already gotten to everybody on earth, what comes along that is 10X the size?

a16z’s Benedict Evans and Steven Sinofsky offer their thoughts on where technology is today, why the perfection of the current crop of PCs signals the category’s collapse, and what happens after the smartphone.

a16z Podcast: What Comes After the Smartphone

Disruption is such an overused buzzword. But the word itself does have meaning: As defined by the Oxford and Merriam-Webster dictionaries, it is a "disturbance...that interrupts an event, activity, or process" and that causes something "to be unable to continue in the normal way". It's also the name for an influential theory about innovation first coined by Clayton Christensen in a 1995 article and later publicized through his 1997 book, The Innovator's Dilemma.

But that was nearly two decades ago! Not only has the concept been much misunderstood and mangled since then, surely it's changed given the advent of new tech and business models today? Is it still relevant, given cases that seemingly defy the theory and its application? Are we at risk of overfitting this "verbally inflated" term to everything, and in doing so, are we missing what disruption theory really says -- and doesn't?

Michael Raynor, co-author of the followup book on disruptive innovation with Christensen -- and author of another book that later tested the predictive power of the theory -- joins this episode of the a16z Podcast to answer these questions and more. He also hints at some nuggets from an upcoming article in Harvard Business Review with Christensen and others that addresses the latest formulations of this theory of innovation.

Our virtual reality-enabled future is arriving, but it’s hard to know -- as it is with every new technology platform -- how quickly we’ll all make the transition to VR and what it will ultimately look like. For example, beyond gaming and entertainment what applications does it seem like VR is best suited for, and will we all be wearing full VR-enabled body suits some day? When will the Matrix become real?

a16z’s virtual reality-obsessed Kyle Russell and Sakunthala Pandit are joined by perceptual and computational neuroscience expert Beau Cronin, to offer their informed opinions on the present state and future of VR. They give the rationale for travel, shopping, and education getting the VR treatment, and why software developers would kill for a VR-enabled dev environment. So strap your “face toy” on and dive into virtual reality.

a16z Podcast: The Present State and Future Possibility of Virtual Reality

As software becomes core to every industry, there is a need for more and more software development across practically every department in a company. But as anyone who has tried to get quality software developed knows, that has given rise to a supply and demand problem.

Leveraging open source software is a big part of the solution to that problem, but venturing into the open source world raises all sorts of questions for most companies. For example, how do you engage as a company in the open source community; what are your obligations to the project; and if you are hiring a development team what clues ought you to be looking for to get the best developers? And what are the developers looking for?

And in the end, who’s responsible and accountable for the all this code flowing around?

In a discussion from the firm’s 2015 Tech Summit, Steven Sinofsky digs into all those questions with a panel that includes Roger Dickey, founder and CEO of Gigster, Slack CMO Bill Macaitis, GitHub Director of Field Services Matthew McCullough, and Joel Spolsky, co-founder and CEO of StackOverflow.

Who has the advantage in artificial intelligence — big companies, startups, or academia? Perhaps all three, especially as they work together when it comes to fields like this. One thing is clear though: A.I. and deep learning is where it’s at. And that’s why this year’s newly anointed Andreessen Horowitz Distinguished Visiting Professor of Computer Science is Fei-Fei Li [who publishes under Li Fei-Fei], associate professor at Stanford University. Bridging entrepreneurs across academia and industry, we began the a16z Professor-in-Residence program just a couple years ago (most recently with Dan Boneh and beginning with Vijay Pande).

Li is the Director of the Stanford Vision Lab, which focuses on connecting computer vision and human vision; is the Director of the Stanford Artificial Intelligence Lab (SAIL), which was founded in the early 1960s; and directs the new SAIL-Toyota Center for AI Research, which brings together researchers in visual computing, machine learning, robotics, human-computer interactions, intelligent systems, decision making, natural language processing, dynamic modeling, and design to develop “human-centered artificial intelligence” for intelligent vehicles. Li also co-created ImageNet, which forms the basis of the Large Scale Visual Recognition Challenge (ILSVRC) that continually demonstrates drastic advances in machine vision accuracy.

So why now for A.I.? Is deep learning “it”… or what comes next? And what happens as A.I. moves from what Li calls its “in vitro phase” to its “in vivo phase”? Beyond ethical considerations — or celebrating only “geekiness” and “nerdiness” — Li argues we need to inject a stronger humanistic thinking element to design and develop algorithms and A.I. that can co-habitate with people and in social (including crowded) spaces. All this and more on this episode of the a16z Podcast.

In her story "Home Base" New Zealander Saradha Koirala tells a slowly churning story set in a children's playground. Despite the youth of its narrator, the story reveals the intense pressure on her to conform both to patriarchal and dominant values.

Saradha Koirala was born in 1980 of Nepali and Pakeha decent and is the author of the poetry collections Wit of the Staircase (Steele Roberts 2009) and Tear Water Tea (2013) and the YA novel Lonesome When You Go (Makaro Press, 2016). She currently lives in Melbourne where she's been working on two more novels and a third volume of poetry.
