Good overview talk, which was fine for a keynote of course, but I'd like a bit more in depth stuff, just my personal preference though. I do think it could've be emphasised that microservices isn't actually a silver bullet, and a monolithic application can actually be better.
Very challenging to follow, and I got lost sometimes. The bits I could understand were great, insightful and speaker is clearly very knowledgeable and excited about crafting this language. Put it all together and it was a really great talk.
