I've been saying this the past few days among coworkers. The one thing Electron proves is that GUI programming is still not where it could be all these years of innovation later, if that were not the case it wouldn't be used as often as it has by as many companies who build their products around it. The reality is that Electron provides solutions to problems that the browser has had to solve for quite a while now: cross-platform development, and gives you a way to write code that already accounts for most of it taking away many of the cross-platform pain points.
