What has Watson been up to since then? IBM has focused its efforts on more practical applications for Watson, including services that are used by doctors, lawyers, and other professionals that need to analyze massive amounts of data. The challenge IBM faces is keeping Watson fresh, with the world's devices producing some 2.5 exabytes of data every day that is expected to blow-up to 44 zettabytes by the year 2020. To keep up with the information overload, IBM announced late last year that it was adding NVIDIA's Tesla K80 processing engines to the mix. Those high performance compute GPUs are playing a key role in Watson's cognitive computing development, especially in terms of natural language processing capabilities.
The result? Watson is more capable and human-like than ever before, especially when injected into a robot body. We got to see this first-hand at NVIDIA's GPU Technology Conference (GTC) when Rob High, an IBM fellow, vice president, and chief technology officer for Watson, introduced attendees to a robot powered by Watson. During the demonstration, we saw Watson in robot form respond to queries just like a human would, using not only speech but movement as well. When Watson's dancing skills were called into question, the robot responded by showing off its Gangnam Style moves.
