World 'running out of computing power'
The world is rapidly "running out of computing capacity", the head of tech giant Microsoft has warned. Satya Nadella said at the World Economic Forum in Davos that superfast quantum computers were needed to solve some of the most difficult problems. Mr Nadella cited the quest to create a catalyst that can absorb carbon, in order to help tackle climate change. This, he cautioned, would likely not be achieved without an increase in computer processing power.
