With Moore's law being dead, efficiency is going to get a lot more popular than it has been historically. I think we're going to start seeing an uptick in the popularity of more efficient GUI programs like the ones you describe.
We see new languages like Nim and Crystal with their only value proposition over Python being that they're more efficient.
Similarly, I predict we will see an uptick in popularity of actually native frameworks such as Qt over Electron for the same reason. We may even start seeing wrapper libraries that make these excellent but complicated frameworks more palatable to the Electron crowd, similar to how compiled languages that look like Python or Ruby are getting bigger.
