Stanford CSP BUS 74. Session 3 Quiz 1.


MIT Technology Review lists face-detecting systems as one of the top 10 innovations for 2017.

The technology figures to take off in China first because of the country’s attitudes toward surveillance and privacy. Unlike, say, the United States, China has a large centralized database of ID card photos. During my time at Face++, I saw how local governments are using its software to identify suspected criminals in video from surveillance cameras, which are omnipresent in the country. This is especially impressive—albeit somewhat dystopian—because the footage analyzed is far from perfect, and because mug shots or other images on file may be several years old.

Facial recognition has existed for decades, but only now is it accurate enough to be used in secure financial transactions. The new versions use deep learning, an artificial-intelligence technique that is especially effective for image recognition because it makes a computer zero in on the facial features that will most reliably identify a person.


Read the entire article and answer the following questions:
1. Does facial recognition covered in the article represent a new technology? Explain briefly.
2. Will the technology become important outside of China? Explain briefly:
2.1. If the answer is yes, what markets/applications will benefit from it?
2.2. If the answer is no, what barriers will prevent its diffusion?

Stanford CSP BUS 74, Session 2 Quiz 2

Mood plays an important role in motivating people for a broad range of everyday activities, both useful and harmful. In a recent study, Stanford researchers discovered a mood-related trade-off between people's short-term and long-term goals:
We tracked the activities and moods of over 28,000 people in real time and demonstrated that people seek mood-enhancing activities when they feel bad and unpleasant activities when they feel good. These findings clarify how emotions shape behavior and may explain how humans trade off short-term happiness for long-term welfare. Overcoming such trade-offs might be critical for our personal well-being and our survival as a species.

Read the study (at least the abstract and intro) to understand the trade-off.

1. Use your imagination to propose 2-3 ways to break the trade-off in order to become happier and more productive in your personal and professional life.

2. Assume that the trade-off is broken by a new, yet to be developed technology. Name 2-3 industries and/or businesses that would benefit the most from the breakthrough.

Founded in 1943, IKEA grew from a small mail-order shop to a major global manufacturing and retail business. Flat-pack easy-to-assemble furniture turned out to be the key innovation that powered the company. For example, the Billy bookcase, originally designed in 1979, sold over 50 million units and is still in production at the rate of 15 units per minute.

Listen to a BBC podcast (9 min) about the Billy Bookcase and read the article about its inventor Gillis Lungren. Using different perspectives, e.g. consumer, retailer, manufacturer, list at least 3 trade-offs that the company broke on its way to global success.

In today's (June 29, 2017) Science News article, Matthew Hudson describes new carbon nanotube transistors created by IBM researchers:
For decades, computing speed has increased as silicon transistors have shrunk, but they’re currently near their size limits. So scientists have been experimenting with carbon nanotubes, rolled-up sheets of carbon atoms just 1 nanometer, or a billionth of a meter, in diameter.

But difficulties working with the material have meant that, for optimal performance, nanotube transistors have to be even larger than current silicon transistors, which are about 100 nanometers across. To cut that number down, a team of scientists used a new technique to build the contacts that draw current into and out of the carbon nanotube transistor. They constructed the contacts out of molybdenum, which can bond directly to the ends of the nanotubes, making them smaller. They also added cobalt so the bonding could take place at a lower temperature, allowing them to shrink the gap between the contacts.

Electrical tests showed their new transistors to be faster and more efficient than ones made of silicon. Silicon Valley may soon have to make way for Carbon Valley.


1. In your opinion, does the new technique create potential for incremental innovation, radical innovation, or both? Explain briefly.
2. Using Backcasting, describe key features of a radically new device that can be built 10-15 years from now, using sub-nanometer transistors.

The Lancet, one of the world's best known medical journals, recently reported that the obesity epidemic has reached a global scale.
If post-2000 trends continue, the probability of meeting the global obesity target is virtually zero. Rather, if these trends continue, by 2025, global obesity prevalence will reach 18% in men and surpass 21% in women; severe obesity will surpass 6% in men and 9% in women. ...High body-mass index (BMI) is an important risk factor for cardiovascular and kidney diseases, diabetes, some cancers, and musculoskeletal disorders.

To a significant degree, the problem is caused by the so-called "Western Diet" that is rich in added sugar and processed carbohydrates. Research shows that the diet negatively affects the microbiota of a healthy person and often leads to chronic diseases.

The problem has a seemingly simple preventive solution: a massive switch to high-fiber diets with emphasis on vegetable consumption. Unfortunately, human food habits are notoriously difficult to change. Moreover, people often think that healthy food doesn't taste good. For example, in an experiment conducted by Stanford University researchers "labeling vegetables with indulgent descriptions led more diners to choose vegetables and resulted in a greater mass of vegetables served per day. Diners chose vegetables with indulgent labeling 25 percent more than basic labeling, 35 percent more than healthy positive and 41 percent more than healthy restrictive."

In your opinion,
1. How would an Ideal healthcare system would address the obesity epidemic?
2. How would an Ideal education system would address the epidemic?
3. How would an Ideal food and beverage industry would address the epidemic?
4. How would an Ideal tax system would address the epidemic?
5. How would an Ideal advertisement system would address the epidemic?

Select at least one of the questions above and describe briefly top 3 features of your Ideal system.

The Services Revolution: Why Social Networks Turned Into an Instituion

Last month I gave a talk (pdf) on innovation timing at OpenWay Club. The presentation covered, among other topics, the unfolding technology revolution in services. The talk drew on several key sources, including the work of Oliver E. Williamson, a Nobel Prize winner in economics from UC Berkeley, Cesar Hidalgo's book "Why Information Grows", and our book with Max Shtein "Scalable Innovation."

My goal was to show that new technologies have fundamentally changed the nature of services because they commoditized "specificity" and "recurrence." (see figures below). That is, in a networked digital world knowing your customers and interacting with them on a regular basis is dramatically less expensive than in a "stand alone brick-and-mortar" world. To illustrate the main points, here's a screen shot of a relevant page from Hidalgo's book (with my annotations) and several slides from the talk.

(The recent purchase of Whole Foods by Amazon is another example of the shift to Groceries-As-Service model, where Amazon leverages its customer insights into recurring retail sales.)

Even more importantly, the new service models have become a major global institution because they addressed the fundamental issue that plagued service businesses since ancient times. Douglas C North (Nobel Prize in Economics, 1993), described the problem in game theory terms:
In the world of personal exchange (recurring-specific - ES), it pays for parties to an exchange to cooperate, because the parties have personal knowledge of the other players and there is the possibility for repeat dealings between the parties. But in a world of impersonal exchange, it pays for the parties to defect, ceteris paribus. With impersonal exchange, the world is one in which there is not an iterated game.... One does not know anything about the other players, and indeed there are a large number of players.
That is, in traditional transactions players on both sides have incentives to cheat because they don't know each other personally or through a personal network. Therefore, in 1999 North suggested that to make the global marketplace efficient and scalable a new model had to be invented:
...we are going to have to devise institutions de novo that attempt to confront and deal with worlds of impersonal exchange.
Remarkably, new service models, such as Airbnb, Uber, Amazon, Alibaba, Instaply and others provide a glimpse of the institutions to come. Since identities of sellers, buyers and recommenders are known, parties are less likely to cheat; therefore, the number and quality of transactions shows rapid growth.  Although the solution is not perfect, it is a lot more efficient than all attempts to introduce global regulations. It's exciting to see how social networking technologies are redefining the rules of commerce and provide a working alternative to law.

LunchTalk: Alan Burdick: "Why Time Flies" (at Google)

Alan Burdick is a staff writer and former senior editor at The New Yorker. His most recent book, "Why Time Flies: A Mostly Scientific Investigation," was published in January by Simon & Schuster.

“In his lucid, thoughtful, and beautifully written inquiry about time — what is it, really? Did we invent it, or does it invent us? - Burdick offers nothing less than a new way of reconsidering what it means to be human.” (Hanya Yanagihara, author of A Little Life and The People in the Trees)

Creative Solution of the Day: the Publication Dilemma

Typically, inventors face a disclosure dilemma: on the one hand, you want to explain your idea to a potential investor or a customer; on the other hand, you don't want to explain it because the idea can be easily stolen. Researchers face a similar dilemma when they consider publishing their results that  might have valuable commercial implications.

In the 1840s, Samuel Colt used the US patent system to overcome the dilemma:
When Samuel Colt, of revolver fame, was trying to sell the U.S. government a system of naval mines, he had to establish that his device was original without giving away its secret. His imaginative solution was to submit the plan to the Patent Office, obtain a confirmation of its originality, and then withdraw the application before the patent was granted, thereby avoiding the publication of the patent specifications.*
The Colt's approach exemplifies a powerful problem-solving technique often called "Separation in Time." According to the principle:
- you perform the useful action first — in the Colt's case: explaining the invention via a patent application — at the time when your potential customer needs to be convinced;
- then you perform a reverse action — withdraw the patent application — at a different time, so that the competition doesn't learn about the idea.

Snapchat provides the most recent example of a successful application of the "Separation in Time" principle along the lines of Samuel Colt's solution. That is, a Snapchat picture or a post is published for a short period of time to a limited group of subscribers; then, the post disappears, so that the information doesn't leak out to the general public. Clearly, the technique can be used for a broad variety of "limited offers."

Lunchtalk: TED - Why humans run the world

A TED talk by Yuval Harari, the author of The Sapiens. From the talk description:
Seventy thousand years ago, our human ancestors were insignificant animals, just minding their own business in a corner of Africa with all the other animals. But now, few would disagree that humans dominate planet Earth; we've spread to every continent, and our actions determine the fate of other animals (and possibly Earth itself). How did we get from there to here? Historian Yuval Noah Harari suggests a surprising reason for the rise of humanity.

Stanford CSP, BUS 152 - Innovation Timing. Session 4, Quiz 1


Recently, a number of technology companies introduced Augmented Reality headsets that enable users to overlay images from the real world with information generated by a computer, including text, video, graphics, etc. Microsoft HoloLens  is one of the most advanced projects in the field, backed by a major industry player. For example, in a 2016 TED Talk, Alex Kipman demonstrated a head-mounted 3D hologram computer that lets users interact with "magical objects" directly, which eliminates, among other things, the need for displays, keyboards, joysticks, and other typical computer accessories.

Please read the wikipedia article referenced above, watch the TED video, and answer the following questions:

1. Is HoloLens a new technology? Explain.

2. Imagine that it is year 2040. Do you see HoloLens-like devices dominating specific fields of human-computer interaction, e.g.

a) Education (certainly, highly likely, maybe, absolutely not). Explain.
b) Gaming (certainly, highly likely, maybe, absolutely not). Explain.
c) Construction and Industrial Services (certainly, highly likely, maybe, absolutely not). Explain.
d) Healthcare (certainly, highly likely, maybe, absolutely not). Explain.

Stanford CSP, BUS 152 - Innovation Timing. Session 3, Quiz 1

Background: Over the last decade, AI-based technologies succeeded in solving various problems that before were considered impossible to solve using computational methods. In one recent example, Stanford researchers "have trained an algorithm to diagnose skin cancer." In another example, AI bot easily outplayed humans in poker.

The significance of the latter development is that the algorithm successfully handled a problem with imperfect information:
Poker requires reasoning and intelligence that has proven difficult for machines to imitate. It is fundamentally different from checkers, chess, or Go, because an opponent’s hand remains hidden from view during play. In games of “imperfect information,” it is enormously complicated to figure out the ideal strategy given every possible approach your opponent may be taking.

Given that innovation fundamentally involves decision-making with imperfect information, we may want to consider how AI will impact broader innovation processes in our society.

1. Assume that AI decision-making services are widely available. In your opinion, which segments of the society will start using such services first: consumer or enterprise? Explain your reasoning and give approximate calendar time estimates for each segment.

2. Consider Kahneman's System 1 vs System 2 approach to human decision-making (e.g. as discussed during our Session 2). Will a wide adoption of AI services improve or worsen people's ability to use "System 2 thinking"? Explain.

3. In your opinion, will AI-based decision-making services affect the overall timing of innovation diffusion in social systems (see Session 1 lecture notes), e.g. by making S-curves more gradual, more steep, or leave them unchanged? Explain.

The public's interest in Bitcoin rose sharply in 2013-14.

For example, on January 21, 2014, in a NYT article titled "Why Bitcoin Matters", Marc Andressen wrote:
Bitcoin gives us, for the first time, a way for one Internet user to transfer a unique piece of digital property to another Internet user, such that the transfer is guaranteed to be safe and secure, everyone knows that the transfer has taken place, and nobody can challenge the legitimacy of the transfer. The consequences of this breakthrough are hard to overstate.
Despite its great promise, this major breakthrough has not materialized yet. Nevertheless, the Google Trends chart above shows a noticeable uptick in Bitcoin-related interest in 2017. For example. a recent post on CloudTech by James Bourne titled "Blockchain beyond Bitcoin: Assessing the enterprise use cases" states that the technology "has serious potential to disrupt a multitude of industries." Also, Cade Metz in a January 6, 2017, Wired article titled "Bitcoin Will Never Be a Currency—It’s Something Way Weirder" reports on the general sentiment about Bitcoin, "Bitcoin is not something the average person will ever use to buy and sell stuff... It’s not something that will improve what the world has, such as money or stock. It’s something that will give the world stuff it has never had."

1. In your opinion, does Bitcoin follow the process generally described as Hype Cycle? Explain briefly.
1a. If yes, what is the current stage of the technology relative to the cycle?
1b. If no, how do you explain the 2014 peak and the significant investments VC funds put into Bitcoin-related startups?

2. Is the 2017 Bitcoin (and related technology) comeback for real? Where would you place the technology on the S-curve and Adopter Distribution chart as of today? Explain briefly.

The Structure of Technology Revolutions

Since last summer, I've been working on a book project tentatively (and modestly!) titled "The Structure of Technology Revolutions." The purpose of the book is to show how technology enables completely new possibilities, by breaking trade-offs that are considered unbreakable.

To demonstrate the underlying structure of the innovation process, I'm using Category Theory tools (OLOGs) originally created by D.I. Spivak from MIT.

Here's a series of draft figures with an example of how the logic of innovation had worked in the technology revolution initiated by the automobile with the internal combustion engine (see below).

 Note, that the same logic can be applied to the modern autonomous vehicle. The technology is going to be successful because it creates incredible maneuverability at the "traffic" level of abstraction.

Now, back to the horses example:

Fig. 1 introduces the trade-off between Power and Maneuverability. An eight-horse carriage has a lot of power, but it's difficult to maneuver. Adding more horses will create a huge maneuverability problem. On the other hand, a horse rider is highly maneuverable but he lacks the carrying capacity of the horse carriage.

Fig. 2 introduces a logical representation of a horse carriage and maps it onto a "Conflicting Desires Diagram." That is, we show that any "designer" of a horse carriage faces a trade-off between Power and Maneuverability.

Fig. 3 sheds horse pictures and shows a logical generalization: a horse carriage is a kind of power-driven vehicle. 

Fig. 4 indicates the desired situation (the green dot on the right): We want a vehicle that has the best of both worlds, it's highly powerful and highly maneuverable.

Fig. 5 shows that the Automobile breaks the trade-off and creates a vehicle with the potential to hit the green dot. That is, we create a technology that disentangles human ability to control horses from the power. Thus, we achieve a new state that was considered impossible before.

To model the Autonomous Vehicle technology revolution we need to abstract from "a vehicle" to "traffic" and show how the new technology breaks the traffic congestion trade-off. In general, congestion trade-offs are ubiquitous in economic systems and technology revolutions break through them quite often.

Fig. 6 is a generalized diagram of how technological innovations make the impossible possible.
