> other than specifying a focus ("video encoding expert" or similar) I am not making a dismissive comment here. I'm saying that expert is only useful for saying things like "video encoding expert". And that a "video encoding expert" may be great in a very narrow way only involving the math surrounding video encoding, or may be a 10x developer in addition, but the "expert" label is orthogonal. I'm certainly not going to pretend to be a video encoding expert in the sense of working on the encoding code at least. I've actually worked on projects that have used video encoding multiple times, and in that sense, yes, I did just "drop in and become an expert," in some cases learning ffmpeg on the fly and in other cases integrating C libraries and dealing with frame buffers. And that is what a 10x developer can do. I don't feel the need to "talk down" to anyone, though, but if an expert makes a claim I will expect them to be able to talk intelligently about it and defend it if it seems wrong.
