Perhaps the biggest announcement at Apple’s iPhone event on Tuesday will be Siri, a virtual personal assistant, says 9t5Mac.

“Apple’s ‘mainstreaming’ artificial intelligence in the form of a Virtual Personal Assistant is a groundbreaking event,” said Siri cofounder Norman Winarsky. “I’d go so far as to say it is a world-changing event. Right now, a few people dabble in partial AI-enabled apps like Google Voice Actions, Vlingo or Nuance Go. Siri was many iterations ahead of these technologies, or at least it was two years ago.

“This is REAL AI with REAL market use. If the rumors are true, Apple will enable millions upon millions of people to interact with machines with natural language. The PAL will get things done and this is only the tip of the iceberg. We’re talking another technology revolution. A new computing paradigm shift.”
