How easy is it to predict where tech will take us in the next decade, and have we hit a plateau in the pace of innovation?

Manuela Saragosa speaks to author and artist Douglas Coupland, who retells how a mind-bending run-in with a Google research team left him convinced that the next huge development hurtling towards us like a meteor is what he calls "talking with yourself".

Science fiction predictions of the future are notoriously wayward - where are the hoverboards and ubiquitous fax machines promised by the Back to the Future films? Nonetheless, forecasting tech developments can be 85% accurate over a 10-year time horizon, according to professional futurologist Dr I D Pearson.

But while tech may continue to take us to new and strange places in the long term, has Silicon Valley run out of earth-shattering new products, at least in the short term? The BBC's Zoe Kleinman reports from a rather subdued CES 2020 tech conference in Las Vegas.
