The Future of Big Data - an interview with John Sontag, VP and director of HP Labs' Systems Research


John-Sontag.jpg20/20 Team:  First, John, can you share what Big Data means to you?


John Sontag: Sure. Here’s one way to look at it: in the future, everyone is going to become a data scientist, whether they like it or not. That’s because we’re moving to a world where, in 10 years, we’ll be creating 20 times as much data as there is now. And it will be all around us, not just in one place. 


The businesses that will thrive in that environment will have employees who can look at the data sources around them and use those sources to improve their customer intimacy, to understand what problems they can solve better, and to build a stronger ecosystem of partners around them to impact whatever sector they serve, be it IT, finance, healthcare, government, or any other.


20/20 Team: Can you give us an example of what that might look like in practice?


John Sontag: I’ll give you one that’s already happened. We’ve been working closely with a number of leading hospitals. Not long ago, a physician at one of these hospitals saw a teenage girl with a very rare medical condition that might elevate her risk of having a stroke. 


They faced a difficult decision – whether to try to give her treatment that would lower the risk of stroke but introduce other risks, such as bleeding. The treating physician hadn’t seen anyone with this syndrome before, and it was so rare that there was neither clinical literature on it nor agreement among the world-class experts in the hospital itself. 


Ten years ago, they’d have been stuck. But this time they were able very quickly to gather data from every patient that had been seen with this condition before and build a virtual cohort for this girl. They could have an accurate assessment of the risks of treating or not treating, seeing what others had done in similar situations, and choose a course of action that was best given the available information. 


They saved her life, and in doing so those doctors just became data scientists. They were able to make a better decision, in real-time, thanks to data. It’s those kinds of experiences that we’re trying to make accessible to everybody who works in a business – where they don’t need to plan for it beforehand, but can quickly assemble data sources, conduct experiments, and gather insights whenever they need.


20/20 Team: And how is HP Labs helping shape where we are going?


John Sontag: One thing we’re doing on the software front is creating new ways to interrogate data in real time through an interface that doesn’t require you to be a computer scientist.  


We’re also looking at how we present the answers you get in a way that brings attention to the things you most need to be aware of. 


And then we’re thinking about how to let people who don’t have massive compute resources at their disposal also become data scientists.


20/20 Team: What’s the answer to that?


John Sontag: For that, we need to rethink the nature of the computer itself. 


If Moonshot is helping us make computers smaller and less energy-hungry, then our work on memristors will allow us to collapse the old processor/memory/storage hierarchy, and put processing right next to the data. 


Next, our work on photonics will help collapse the communication fabric and bring these very large scales into closer proximity. That lets us combine systems in new and interesting ways.  


On top of all that, we need to reduce costs – if we tried to process all the data that we’re predicting we’ll want to at today’s prices, we’d collapse the world economy – and we need to think about how we secure and manage that data, and how we deliver algorithms that let us transform it fast enough so that you can conduct experiments on this data literally as fast as we can think them up.


20/20 Team: Could you talk a little more about the impact of the new hardware you are developing on how we use software?


John Sontag: Sure – the combination of non-volatile, memristor-powered memory and very large scales is causing the people who think about storage and algorithms to realize that the tradeoff has changed. For the last 50 years, we’ve had to think of every bit of data that we process as something that eventually has to get put on a disk drive if you intend to keep it. That means you have to think about the time to fetch it, to re-sort it into whatever way you want it to rest in memory, and to put it back when you’re done as one of your costs of doing business.


If you don’t have those issues to worry about, you can leave things in memory – graphs, for example, which are powerful expressions of complex data – that at present you have to spend a lot of compute time and effort pulling apart for storage. The same goes for processing. Right now we have to worry about how we break data up, what questions we ask it and how many of us are asking it at the same time. It makes experimentation hard because you don’t know whether the answer’s going to come immediately or an hour later. 


Our vision is that you can sit at your desk and know you’ll get your answer instantly. Today we can do that for small scale problems, but we want to make that happen for all of the problems that you care about. What’s great is that we can begin to do this with some questions that we have right now. We don’t have to wait for this to change all at once. We can go at it in an incremental way and have pieces at multiple stages of evolution concurrently – which is exactly what we’re doing.


20/20 Team: What kind of impact do you see these changes having on businesses and on our lives more generally?


John Sontag: One thing is that there are people who have given up on thinking about certain problems because there’s no way to compactly express them with the systems we have today. They’re going to be able to look at those problems again – it’s already happening with Moonshot and HAVEn [HP’s Big Data platform], and at each stage of this evolution we’re going to allow another set of people to realize that the problem they thought was impossible is now within reach. 


One example of where this already happened is aircraft design. When we moved to 64-bit processors that fit on your desktop and that could hold more than four gigabytes of memory, the people who built software that modeled the mechanical stresses on aircraft realized that they could write completely different algorithms. Instead of having to have a supercomputer to run just a part of their query, they could do it on their desktop. They could hold an entire problem in memory, and then they could look at it differently. From that we got the Airbus A380, the Boing 777 and 787, and, jumping industries, most new cars. 


I am absolutely certain there are lots of problems like that – that at present are just too big – and where applying this new compute power will offer us a totally new insight on the world.  We’ll see it in retail, in finance, in healthcare, everywhere – people stitching together the information that’s in their ecosystem to more effectively connect the dots. It’s an exciting time.
