A note slightly related: Mars reaches perihelic opposition with the sun on July 27, 2018, which means observers on Earth will have their closest view of the planet since 2003. Great time to borrow a telescope.
If someone spend many months learning a new language, but still can't be able to build something functional with it, I think he has a bigger problem...
It's wrong because that tends to persuade developers that there is one tool for every situation.
If you build something functional fast with your favorite tool (not suited for the job), then you will probably spend many months maintaining/hacking your codebase to keep it functional and well designed.
"Electron has lowered the barrier to developing desktop applications". Nope, I don't think so. Perhaps for web developers.
For non-web developers, there are already well-suited technologies to develop desktop applications: Swing, Qt, Cocoa, GTK, WPF/WinRT, and so on. Maybe theses technologies seem less sexy but there are here from the beginning to do that kind of job.
