Yes. Still one of the best batteries included web frameworks for creating anything that's more of a website (e.g. E-Commerce) than a web app (e.g. Photoshop). No, you don't need NextJs and friends for everything ;)
Is Groovy/Grails still popular? I also remember Groovy++ but I believe its features were incorporated into Groovy. But maybe these are already present in modern Java?
I don't think vision is the ultimate API. It wasn't with "traditional" RPA and it won't with more advanced AI-RPA. It's inefficient. If you want something to be used by a bot, write an interface for a bot. I'd make an exception for end2end testing.
You're looking at it from a developer's perspective. For non-developers, vision opens up all sorts of new capabilities. And they won't have to rely on the software creator's view of what should be automated and what should not.
Most non-developers won't bother. You have shortcut on iOS and macOS which is like Scratch for automation and still only power users use it. Others just download the shortcut they want.
wireframesketcher[1] seems to do the same than Konty and runs on linux. I'm not related to them in any way but use this solution for years and I'm very happy with it (paying customer).
