Let me add briefly that Canada has a number of companies that work in artificial intelligence. We've referenced the idea of big data. Maybe I'll come back to that very quickly for one moment.
With the amount of information we are now able to collect from a variety of sensors, we can transmit large volumes of data, put them in databases that are now much more powerful, apply software to them to do data mining, and then create machines that can recognize the patterns they see in the types of information being provided; and, to go one step further, we can create an algorithm that will give you a set of decision functions that you as a machine will go through and come up with an answer that shows thinking or judgment, and be able to manipulate that data—which the machine itself is able to do to demonstrate that it is learning and is applying judgment.
We have companies in Canada that, for example, can help with learning for, say, pilot training to better instruct the pilot on how to respond to changes in weather and the patterns as they're learning to fly a plane. The machine is able to help them anticipate better some of the influences that could happen, based on the data they are evaluating.
