Right.
If we think about just the simple cost of investing in research in a partnership, we have to weigh that against the cost of just bringing researchers on board as part of the team and doing that research in-house. When we think about emergent fields like AI and machine learning, there are a lot of collaborations forming and efforts under way to build partnerships, which we of course want to be part of. We also have to think about our own commercial interests and bringing on staff with those skills. Many of those might come out of either other AI companies or universities and colleges where they're doing research in that area.
