I'll assume you're a programmer. Have you ever been in a situation where your IDE, text editor, or other tools were extremely slow and unresponsive? You're trying to perform some task and there's this external bottleneck slowing down everything you are doing. Instead of completing the subtask quickly so that your train of thought flows smoothly into the next unit, the flow is interrupted by having to wait. And once you're out of the flow, there's mental effort required to get back into it. But if your tools present a constant bottleneck, then you are permanently stuck in this less efficient mental state. Essentially the bottlenecking tool becomes a part of your mental model, and that useless chunk of mental real-estate reduces what can be accomplished by the same mind unburdened by this useless detail. But all of this goes just as much when a lack of typing skills is the constant bottleneck. If you can't type at the speed of thought, the quality and complexity of your thoughts suffer since a part of your working memory is consumed by the process of typing. This has real implications for what you're able to accomplish.
