What does PWA stand for? As an Android developer I am kind of wary of how they push Kotlin for Android. I'm sure it is good, and I enjoy learning a new languages, but I already have a code base that I am worried they are going to make me rewrite.

Progressive Web Apps. Basically Web apps packaged in such a way that native APIs can also be exposed as browser APIs. The Chrome/ChromeOS teams started with it, and Microsoft adopted them to UWP as well. Safari also kind of support them. https://developers.google.com/web/progressive-web-apps/ https://developers.google.com/web/progressive-web-apps/ https://developer.microsoft.com/en-us/windows/pwa https://developer.microsoft.com/en-us/windows/pwa Plenty of talks at Google IO and BUILD.

Kotlin once compiled is (for practical purposes) indistinguishable from Java. Even if new APIs will be Kotlin only (Jetpack Compose), you can write new Kotlin code alongside your legacy Java with no issues.

  OK I get that it becomes the same byte code but I fear whatever conversions and updates are necessary. Probably irrational.

  Not really, because Kotlin uses concepts that aren't exposed in Java the same way, let alone the clunky J++ used by Android. For example extension methods or suspend functions. Hence why there is a guide on how to write Java friendly APIs from Kotlin. Jetpack Compose is an interesting story, looks like it sprung into existence as response to Flutter, without any concrete ideas on how tooling should look like and total disregard for the ongoing efforts to sell constraint and motion layout editing on the graphical tooling to android devs still using the old layouts. Having watched all SwiftUI tooling related talks, and from experience how Android Studio has evolved, I don't have great hopes that by Google IO 2020 we will see demos at the same level as WWDC 2019 SwiftUI ones.
