It really depends on which part of "Game Development" you are talking about. What most of the people agree is that Rust can deliver value to the core and to the performance focused components in the game engine. I assume that's what this article is talking about too. But beyond that it's hard to see it eating the market in other areas. You really want to have some easy to find average coders that can pretty much script your game on top of an engine and framework, and you don't want to spend way too much on them. It could be a different story for some multiplayer AAA games since they have enough lifetime to become mature and start to take every optimization opportunity.
