 Well, what's fascinating to me and having this like my third or fourth re-invent is just the volume of new announcements that come out. It's impressive, right? I mean, it's impressive in terms of number of services, but then the depth of those services and the building on, I think it's just, and it's really amazing. I think that the trend you're going to continue to see and there's going to be more keynotes tomorrow, so I can't let anything out, but just AI, ML, really excited about that analytic space, serverless, just continue to see the maturation of that space, particularly for startups. I think that to me is what's really exciting and just seeing folks come together, start exchanging ideas.
