I am wondering if there will be a follow up or response thread?
There's a lot of good feedback. It was good to see inside Lars's head, and what is not. I think he got a lot right, thought I'm scratching my head on the AI comment. There's two things I'd like to bing up though.

The first thing that stuck out is others mentioned and I re-iterated, is comparing Qt to Google's Flutter. It seems to have significant overlap with Qt (Even the Dart syntax is declarative-like) and I see it as probably the end of Qt, unless Qt 6 can differentiate. If I were a developer starting out today, I'd probably choose Flutter.

Next, IMHO Qt is not doing enough to target enough developers, and this is where I have to re-iterate that QML should be an open web standard. (QMLWeb https://github.com/qmlweb/qmlweb , has atrophied) If you can capture the market of Web developers, that's the biggest developer market there is. Where I currently work we have a standing order that all software should be web-based except for the code that runs on devices (Arduinos and Mobile) which can't. Now I got Qt and a license for mobile before Flutter was a thing, so my work is grandfathered in, but we're likely to move to Flutter at some point because the web team can help out with that. Also, flutter's Web support is still a "tech preview" https://github.com/flutter/flutter_web/blob/master/README.md

Big fish, small pond vs.  small fish big pond. But the small pond is drying up. C++'s modernization efforts are too little to late, and hardly feel that I have a clue what's going on in modern C++ despite writing c++ for 20 years now. And with the new async/await it's only going to get worse. QML has to be the primary language for Qt 6, and it's got to work on the web to at least stay in contention with Flutter. My boss balked at it at first when I mentioned C++. He thinks it's too hard for most developers to do right. (And he's right). QML saved the day.

Not only that but Qt's licensing is far more complicated than the BSD-like license of Flutter. But you've got to be careful about what's LGPL, GPL, commercial, or "other". 

Anyway, I don't know if it's a good idea to start this thread but not everyone follows the blog. ¯\_(ツ)_/¯


I really like Wt (Witty, Qt4-like widgets for the web https://webtoolkit.eu ) But I'm hoping with the new Wt HTTP server we can get a HTML/QML client to talk to a Qt model server, the same way Wt works. I think WASM and WebGL are the wrong way for Qt to target the web.
