Flutter 2
We're all complaining about how js is a bad language, tooling is a mess, and how the web is fundamentally built for documents and makes it hard to create app-like experiences. Now, Google comes and creates a whole new UI toolkit from scratch, couples it with a very beautiful SDK and component framework and offers a far better programming language than js could ever be but we're still nagging. I was also pretty disappointed with the demo at flutterfolio.com that is supposed to show how great Flutter 2.0 for the web is. It's not that good but it's gonna get there eventually, given the hype around wasm and  technologies. Not to mention that Flutter is already better and easier to use than the existing native tools for both Android and iOS. I believe Flutter is an extremely ambitious project and I appreciate that Google is really trying to give an answer to the problem of cross-platform UI development.
