The sheer scale of technology on show leaves me thinking that the "Light" in the expo's title "The Light of the Internet", is a reference to Greek mythology and the story of Prometheus, who stole fire from the gods so that we could light and warm ourselves in our caves. Except now we're in charge.

By far the best technological treat on show is from Tmall.com, who seem to have invented a supermarket with no people in it to annoy you and where you don't have to pay. Sadly, I'm informed that it is their "unattended supermarket" which, once you've scanned a QR code on entry, allows you to swipe what you like off the shelves and leave. When you pass through the exit your phone will be charged however.

If that is not enough to scramble your circuits, you should see what iFlytek has to offer. The Chinese tech company has developed a handheld device which looks like a modern twist on a Star Trek transponder that can interpret any known alien language in the galaxy. Okay, that last bit isn't true, but it is able to instantly (and I mean instantly) and accurately (I mean that too), translate your speech to Chinese, English, French, Korean, Japanese and Spanish. You'll never be caught short looking for a pharmacy in a foreign country ever again.

After a day's exhaustive trip into the future of the world today, I can't help but think that this might all seem passé to someone in 20 years' time who has his own robot butler and smart phone implant in his eardrum.

Emblazoned above a sunburnt orange driverless car, which looks like it could be fitted with a flux capacitor, there is a slogan that reads "What's next?". Indeed, what is next? And if you can answer that question, then my guess is you could end up a rather wealthy humanoid, indeed.
