Mark Zuckerberg, Marissa Mayer, Steve Jobs offer lessons on technology use

There's no question that the tools created by the likes of MarkZuckerbergand Steve Jobs are shaping our lives. But whatlessons can we glean from looking at the way tech titans approach technology and privacy in their personal lives?

Facebook CEO Zuckerberg has famously said that sharing is the new social norm which has replaced privacy. He toldthe crowd at a 2010 technology awards show,"People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people."

Facebook relieson that kind of openness. Our willingness to share information online directly impacts the massive company's even more massive bottom line. After all, none of its billion-plus active users pay a cent for use of the social network at leastin dollars.

But back in 2013, when it came time to put down his roots, the Facebook exec bought up all of the neighbouring houses around him as a buffer from the world, according to reports.

Maybe that's lesson number one actions speak louder than words. It's one thing to say that privacy is dead, but when it comes to the way we live, our desire for downtime, and the instinct to protect the ones we love, we might say we're comfortable sharing everything but only if we have the option not to.

Yahoo CEO criticized over parenting choices

A lack of privacy has enveloped Yahoo CEOMarissaMayer recently. She'sfacing rumours that her time as the head of the company is limited.

But much of the chatter around her has been about the way she is raising her children, and the brevity of her maternity leave.

Part of this is genderedfemale executives face far more scrutiny over their personal lives than any male leaders.

When's the last time a male CEO had to debate whether or not he could "have it all," and truly excel at being both a businessman and a father?

But this alsospeaks tothe conflict between the promise of technologyand the social standards set by the actions of executiveslike Mayer.

The mythology of theinternetis that we can work from anywhere. However, it also means that wherever we are, and at whatever time of day, work never truly stops.

Our devices promote an "always on" culture of increasing work pressure, and decreasing boundaries between work and home life.

While Mayer's two-week maternity leave may be an extreme case, it sets an example that ripples beyond the Yahoo boardroom. Despite the promise of the freedom to balance work and home through our connected lifestyles, we ultimately sacrifice time offandthe sanctuary of home so we can always work.

Apple CEO Steve Jobs limited kids' screen time

And then there's the hotly debated issue of screen time.

It may come as a surprise to hear that Steve Jobs, the late Apple CEO, was a self-proclaimed low-tech parent, telling the New York Times helimitedhis kids' use of the very tools he created while they were still young enough to be impressionable.

Here we are, living in an age in which tablets can be found appeasing restless toddlers in strollers around the world, and yet the godfather of the mobile device would never have allowed the same for his kids. It's likea fast food executive insisting that his children be vegan and makes you wonder what Steve Jobs knewthat the rest of us don't.

When it comes to technology, there is often a sense of "do as I say, not as I do." And that's true of the leaders of industry, as well as parentsand teachers. We think we know what is best, but often don't follow our own advice.

Don't let technology use become second nature

But it's not entirely our fault. The technologies that we welcome into our lives are designed to seamlessly enhance our experiences. And as such, over time, we lose sight of them.

It's sort of like driving. When you're a new driver, you're reminded to consciously check the rear-view mirrors every few seconds. But after a decade of driving, that becomes second nature, a behaviour you're no longer conscious of performing.

The same is true of our digital encounters, from what we post and share onlineto putting an iPad in front of a toddler without giving it a second thought. The allure of the tools is so great that we sometimes lose track of how they're shifting our behaviour and in turn, shaping us.

So maybe it's time to take a closer look at the leaders in the world of tech and not just the tools they create but how they choose to use them.
