My main issue with using the general chatbot is that it's an incredibly inefficient way to convey information. For writing tasks I essentially need to type most of the answer first to get reasonable outputs when considering my actual constraints.
More specialized tooling will have these constraints built-in, which will increase productivity.
Even if we have the perfect general chatbot, it's still a lot of work to concisely describe your requirements to it.
I guess that since Epic owns Unreal Engine that bad news for Epic means good news for Godot?
I don't think that Epic is going to want to divest from Unreal considering how much money it makes.
I also don't think that it's a zero-sum game. As a developer I want Unreal (and Unity) to be great so it creates more competition. Unreal has led the way in a lot of cool gaming tech that Godot is picking up.
