Those are the potential barriers in the future, issues that have to do with medical legal issues. For example, if you are in Halifax and you are taking care of a patient in Toronto, who is responsible? Is it you or someone else? Of course there is also the issue of remuneration.
However, there has been a lot of work done already in telemedicine, which has paved the way for this next stage, which is remote presence in medicine. Those barriers will be worked out over time.
When I said that technology is unstoppable, I was talking about the idea that 20 years ago you had to go to a bank and stand in line if you wanted to take out $10. All the issues that have to do, for example, with encryption and security have already been worked out. People, believe it or not, are more concerned about their bank account than they are about their health. They are willing to put in their data in terms of managing their account. The regulations will come together. Technology is obviously so helpful that as it advances, all these regulatory issues will have to accommodate this technology. That's what will happen in the future.
