Fair question. The desktop is still around. As long as plain old laptops or desktop machines are required (which is still a high percentage of computers) and there are developer who want to write lean platform independend applications, Qt has a good chance to being considered. The embedded market is very attractive for Qt. Actually it is also very suited for server side applications and supported async style long before Node.js was invented. The mobile market is likely lost though, and technologies like Dart/Flutter will also go towards the desktop and already support web development.
