2020: The future of technology revealed

What the next 10 years holds for us all

Bumps in the road

But before we wire our bodies, we need a far more secure network than today's internet and better privacy safeguards for the petabytes (1,024 terabytes) of consumer data that an always-connected world will generate, says Pradeep Khosla, co-director of Carnegie-Mellon University's CyLab.

RSA chief scientist Ari Juels believes biometrics and encryption will help with security, but trouble may still arise when data reaches users' screens. Context-smart back-end systems will help. "They'll know that, if you're in San Francisco, someone in Thailand shouldn't be using your credit-card number," Juels explains.

Khosla says that a combination of technology, education and tough legislation against "the abuse and misuse of information" is the best way to surmount the privacy hurdles that remain.

Liebhold adds: "I don't think it's a foregone conclusion that our privacy will be lost or that it will be protected. We have control over the future."

Tiny cameras and wireless connections may herald an era of 'sous-veillance', as cameras and mics in your glasses or shirt buttons record every moment, upload it and let you replay the action.

Steve Mann, a Toronto University professor, has used wearable devices to record nearly all of his waking life since 1980.

"Imagine recording every conversation you've ever had with your spouse," says Jamais Cascio of the Center for Responsible Nanotechnology. "That kind of easily searchable memory will change what it means to be a person."

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)
