Nothing could be more embarrassing. Microsoft CEO Satya Nadella tried to demonstrate Cortana, Microsoft’s voice command software and rival to Siri, and failed miserably. Nadella was left red-faced when Cortana failed to hear his commands correctly. Nadella said to Cortana: “Show me my most at-risk opportunities,’ Cortana heard: ‘Show me to buy milk at this opportunity’. A visibly embarrassed Nadella tried to make light of the situation, because clearly there was no use crying over spilt milk.
