Masayoshi Son, chief executive of SoftBank Group Corp., believes that within 30 years, artificial intelligence will be smarter than the human brain. The Wall Street Journal reports that Son made the prediction at Mobile World Congress, the telecom industry's biggest trade show, which is currently being held in Barcelona, Spain. Not only does Son think that super smart robots will outnumber humans in 30 years, but more than a trillion objects will be connected to the internet. "That is why I'm in a hurry to aggregate cash to invest," he said. SoftBank has made quite a few recent deals, including purchasing British microprocessor designer ARM Holdings PLC for $32 billion, as well as U.S. asset manager Fortress Investment Group PLC for $3.3 billion. Son plans to ramp up the research-and-development funding for ARM, which designs the basic architecture for chips in more than 95 percent of smartphones around the world.
