Artificial Intelligence: The Single Biggest Threat to Apple Inc. (NASDAQ: AAPL)

For over a decade now, the biggest selling points of premium smartphones have been all about physical design. But in the coming years, the consumer electronics market is poised to experience a radical shift -- one that every investor should start paying attention to today. When Steve Jobs officially unveiled the first iPhone to the world in 2007, there was enormous hype surrounding its groundbreaking touch interface -- and for good reason. By blending input and display into a single place, Apple managed to redefine the mobile device entirely. In the years that followed, Apple introduced a great number of incremental improvements and it was always the physical redesigns that stood out and spurred sales the most.
