I read an interesting thread about this in relation to game dev. Development is ugly, so a lot of audience building and investor potential comes from creating visually appealing gameplay demos and mechanics. Often they are made separate from the core of the game. All that time spent making engaging content ends up compromising the development process and turning it into more of a show reel, rather than a fully functioning holistic game.
That is fine if you're doing it for yourself, but rather unhelpful if you hope to make a living out of doing the thing. The people I know who make a living off their art are those who sink a lot of time into selling their art (and themselves). Those who sit and home and just make (often much better) art languish in obscurity.
I’d rather do the thing than talk about it. Or, frankly, watch/listen/read others.
