 There's any number of advances, so of course on the algorithmic side, on the mathematical side people are constantly advancing and it's very fascinating to watch that. And of course we have a huge increase in computing power and decentralized computing power and this enables us to do fascinating new things. Well you're exactly making the point we would like to make because the promise of the new 5G network connects us much closer to the domains like automotive or health or smart cities and with the distributed compute resource and 5G networks we are able to come closer to where the problem is. And our aim is that we can tailor make our AI applications so that we have a powerful back end where we have the heavy computation which takes longer time but that we can utilize what we're having in terms of computing power very near to the problem for very swift reactions. It's very necessary to have such a virtue to bring different people together. What's missing here is the customers, the application domains, in fact the point has been made that there's too many of them. They might distract what this group is about but it's very necessary to learn about the academic advances we have and what the suppliers and vendors are offering and of course for us as a carrier it's very helpful to see how other carriers are integrating the whole stuff which is quite a job actually.
