Not a fan of electron at all. But I think it points out the direction for the future of gui. There's a whole generation of new languages (rust, go, dart, D, ...) that wants to get into the gui-space and finding QT and GTK problematic. QT is known for "using every C++ feature", making it less than ideal for bindings. GTK is not very cross platform I think, and is criticized for beeing gnome-centric. Both toolkits are object-oriented, making them a poor fit for any language that is not. Something like mozilla's webrender could be used in a more language agnostic way (declerative, reactive), while having the support required for the gargantuan task of a graphics/toolkit backend.
