How will smartphones look in five years?

Business Insider posed this question to Aparna Chennapragada, a Google director, at the Web Summit tech conference in Ireland last month.

She described a future in which technology does "a lot more of the heavy lifting," apps are de-siloed, and the information that users want proactively comes to them.

Chennapragada heads up Google Now, Google's virtual-assistant app — and as such, its features and the philosophy behind it appear frequently in her vision of the future of smartphones.

And she's not alone in her belief in the power of virtual assistants: Just about every major player in the tech industry is developing one right now.

Here's why Google thinks they're the future, and what one of the company's key architects has planned for it.

'Mobile changes everything'

"I start with this super clichéd statement — from the Department of Obvious," Chennapregada jokes at the beginning of the interview. "Mobile changes everything. I say that, people are rolling their eyes, like 'come on, everyone knows this.'" Nonetheless, she highlights three "key shifts":

"On a phone, you want answers on the go. You don't have time to wade through screens. You want quick answers on the go. That's the first shift.

"The second shift ... unlike desktop, where the search engine was synonymous with finding information ... phones are about getting stuff done. [It's] about playing music through Spotify, or calling a cab using Uber ... In some sense it's not about getting answers, it's about getting stuff done.

"The third shift, which is closer to my heart on Google Now ... because [the phone is] such a partial-attention device, you want the information to find you, not just for you to find the information. And that's a big shift. It's a big shift certainly for new companies, and it's a big shift for Google as well."

'Assistance is the new black'

Virtual assistants are one of the trendiest themes in tech right now. Google has Google Now. Apple has Siri. Microsoft has Cortana. Facebook has M. "Assistance is the new black," Chennapragada says. "The core job for us at Google in this new world is about assisting users ... it's how do you get your answers fast, how do we help you get stuff done."

It's a new role for Google, which has historically been content to serve up huge amounts of data and let users search through it themselves. But people are now on the go, and need the right information to find them.

This is what Google Now does. It learns your routine, and information you might need proactively finds its way to you: Whether that's the weather, sports scores, road closures, or your schedule — the user gets the information they need (or that Google Now thinks they need), without ever having to "search."

And this shift throws up new challenges. "Here, the product is a very high-promise product. What I call the ratio of wow-to-WTF is much has to be much higher. What I mean by that is that if you get the wrong answer [when] you search for Donald Trump — you get the second-best article, it's not a big deal right? But if we told you 'hey, your flight is delayed, don't worry about it,' and the goddamn thing is on time ... WTF, right?

Chennapragada adds later: "The stakes are way higher."

Avoiding the 'creepy line'

Also speaking at Web Summit, David Marcus — the ex-PayPal CEO who now heads up Facebook Messenger and M, Facebook's virtual assistant — discussed the concept of the "creepy line." For virtual assistants to work well, and work proactively — anticipating your demands in advance — they need a lot of data on you. At what point does this get weird or "creepy?"

"While this is a very popular theme for news, I think there’s zero creepiness when there’s a lot of utility," Marcus said. "The minute it gets creepy is when a company gets a lot of information and doesn’t give anything back."

When I asked Chennapragada, she had a slightly different response — emphasising user choice. "I've thought about this problem, oh I don't know, for four years now? There are two fundamental principles. One principle is user control. The user agency. The user needs to be in the driver seat. Take Google Now, for example — basically saying the user is hiring the assistant — they're saying 'Hey, use this data for my benefit, here's the set of benefits that I want.' It has to be a user opt-in. That's one.

"There's a complimentary thing about transparency that is, it's not just about agency — it can't be a black box. So in our case, for example, [we say] the location history is useful because when you're on your way to pick up your child from the day care you kind of need to know where you are, to tell you about the traffic incident ahead.

"These two things go hand in hand."

Google Now is just getting started

Over the long term, Google Now wants to be all things to all people.

Chennapragada didn't discuss usage numbers, but very much frames Google Now as in its infancy. She talks about "early steps," and an elementary focus on "actually [making] sure the experience works right."

Over the long term, Google Now wants to be all things to all people. But right now? "I'll give you the honest picture here ... when we give [users] assistance for enough points during the day or week, [they] find it super useful ... [but] what we do find is in certain markets and certain users ... [we don't have] many useful things to say yet."

She highlights a feature in Google Now that helps you remember where you park your car: "Awesome feature, everyone in the Bay Area who has parking woes, they love it." But a user study carried out in Mumbai, India, provided a "reality check."

A Google researcher explained the feature's possibilities to a user in Mumbai, "and the guy just stares at him for a while, and says: 'I jump off a train every day.'

"I'm laughing now, but I was like 'holy s***!' We really need to figure out what works for different markets."

And despite being one of Google's chief architects of the virtual-assistant revolution, Chennapragada thinks the state of the tech is overhyped right now. "Really, I think we underestimate where we are in the cycle of the whole assistant-based [app], " she says. "On demand is all the rage right? ... Assistance is like opinions, everyone has them. The parallel for me is the 1990s web — it's just getting started ... There's an order of magnitude more users, five billion people will be online in five years, and suddenly this actually has the ability to affect the real world ... we want to make sure that we're building the blocks right."

The five-year horizon

"I want to see two things happen as a user ... one thing is, I really want the technology to be doing a lot more of the heavy lifting. Specifically, for example, I want information and the right information to find me. Today, if you think about these 3.5 billion [users who] have these phones, and they're all turning into broadcasting devices. So in a world where everyone's talking, you need selective listening."

In short: smart, AI-driven filters, capable of finding the signal in the noise, without the user having to exert themselves.

"I think the other thing is: 'What happens to the next generation of apps?' is a really interesting question. I personally think we can de-silo and unbundle the function of apps. So apps are a means to an end right? For many of these services they're a way for their functionality to get to users."

Take Spotify: Users don't care whether it comes via a dedicated app, or a desktop webpage, or an embedded widget in another app, just so long as they get the functionality — music streaming — they want.

It's a vision that is slightly different from Facebook's plans for Messenger, which would see huge numbers of apps replaced by threads between users and companies in the messaging tool, or interactions handled directly by virtual assistant M.

Chennapragada wouldn't comment on Facebook's plans — but disagreed the future lies in eliminating apps. It's "less about disintermediating apps [and] more about de-siloing apps." Google has made some "early steps" with app indexing, letting you search inside apps. But "even now with Now On Tap, it's so difficult for users to jump between these contexts, jump between these apps. And what we're saying is that needs to be far more fluid ... [It's] less about shrinking them, or obliterating parts of the app, but about saying: 'There's so many more places where parts of your app can surface.'"

Hardware limitations

Chennapragada also suggested that the hardware in modern smartphones can still be a limiting factor in what is achievable. She brought up a bug report from a user about Google Now — again, the feature that helps users remember where they park their cars.

"So we got this bug — and I'm not saying this is a normal bug — but we got this bug from a bug report." And the report says "'Hey, I just got off my jet, and you think I parked my car' ... And I was like 'that's not a problem for most of our users!'"

This highlights the problems Google can face building problems for billions of users: There are an unthinkable number of variations an potential use-cases — and right now, "the hardware signals are not yet there" to account for all of them.

"We could go really invest a lot more in sensors and then get there, but given battery life, and where things are, it's not really so wise. So we said, you know what, we'll try to make this work with x-percent of accuracy and we live with that."

So is the vision for mobile ahead of the reality? "Not specific to Google Now, but any of these things, when we say this 'contextual computing' as such, there has to be innovation all through the stack."
