UI fashions come and go, but the terminal is forever.
My gripe isn't that there's anything inherent in GUIs that makes them a less reliable interface than the terminal, it's that getting them to the same level of dependability appears to take more time. And, for all its warts, the fashion du jour of making a GUI by just dumping HTML+JS in a browser instance is something I whole-heartedly support, because it gives application developers probably the simplest (today) wide-spread technology to build GUIs with. It almost always results in applications that consume too much RAM, too much CPU, aren't native-looking, and there are probably other easy GUI-building solutions (QML?), but at the same time they're trivial to edit, quick to write, and there is a ton of documentation and a large community around them. I really hope that electron becomes a standard installable application platform in the near future.
