What year will artificial intelligence surpass human intelligence?

In an article published last year, entitled “When will AI exceed human performance? According to data from artificial intelligence experts, elite artificial intelligence researchers predicted that “human-level artificial intelligence,” or HLMI, has a 50 percent chance of being produced within 45 years and a 10 percent chance of being produced within 9 years. But anyone who has ever had a conversation with Siri or Cortana (some of the virtual assistants currently on the market), could argue that HLMI is already here.
