First of all, you can ask your nephews to be Canadian recruiters and bring their girlfriends to Canada.
There are always areas that we are discovering, just like we're discovering new knowledge, and those areas of discovery are quite often between disciplines. When we bring disciplines together, we get an exchange of different ideas and perspectives. Questions become more richly considered and developed, and the product of the research is better.
When you try to build a model, for example, on the computer simulating a problem, you can build a very simple model and it will give simple answers, but the answers that you need are actually very complex. You need not just consider, for example, that a road would be built ergonomically, but that it should be environmentally and economically done, and it should be done in a way that's culturally supportive of the people's needs. That way you get a road that's really good. When we bring researchers together, that happens.
One of the things we are doing more and more in Canada is creating environments where there's not just the collision of atoms but the collision of minds and people sharing ideas to make new discoveries. That's really exciting and it's happening right across the country.
Recently I've heard about artificial intelligence mixing with agriculture, artificial intelligence mixing with medicine, neuroscience, oceanography mixing with nanoscience. There are all sorts of new possibilities that will come from this collaboration and bringing together of new ideas and people.
