Not sure how to say this without sounding like a bit of an asshole, but why should we care? What does Theia do better than VS Code? For some relevant context I don't consider VS Code to be a good IDE, but it's not a bad editor. I use it when I need to crack open some random file (typically markdown or JSON) with maybe a bit of syntax highlighting, but I would never use it for programming.
Article was a bit light on who the intended audience is for Theia. VS Code's big selling points are that it's super fast to open and has a robust extension ecosystem, is Theia going to provide the same, and how are they planning to convince current VS Code users to switch?
