There’s an interesting note on François-Henri Pinault’s official bio page on the Kering website.Aafter a the usual title/school/professional background stuff, the last line is: “He takes a personal and professional interest in sustainability and the development of e-business.”

It’s the last bit that struck me, given that on Tuesday M Pinault (left, with wife Salma Hayek), through his holding company Artemis became a meaningful investor in Square, the mobile payments company started by Twitter guy Jack Dorsey.

CES this year has been a sprawling, lively affair with errant film directors on stage, bendy TVs and more drones than you can shake a stick at, but one clear theme has emerged: a lot of tech companies are betting that in the near future, everything will be connected to the internet, all the time.

The annual extravaganza for gadget geeks doesn’t officially begin until tomorrow but there is already plenty happening. The FT’s Hannah Kuchler, Tim Bradshaw, Paul Taylor and Matthew Garrahan are in Las Vegas to cover the show, which Hannah says is marked this year by the presence of companies from outside the traditional consumer electronics industry, from healthcare to cars.

But even as technology becomes more integral to products across the board, the market for technology products in 2014 will likely decline, according to forecasts released by the show’s organiser, the Consumer Electronics Association. Read more
