So artificial intelligence is an important part of Unisys' security services? 

Artificial intelligence is a boon for that. It's a boon for predictive analytics. And therefore it becomes very important for us. That's one example. But it really is table stakes. I would say, in the last 24 months, blockchain has become table stakes, too. And blockchain can be an important element in securing a supply chain. And supply chains are critical. Very few companies make everything that they sell. And very few companies are not extremely dependent on supply chains. So the more you can secure the providence of your supply chains, the better. And blockchain is perfectly suited for that.
