People often say things like "I think slower than I type", but I don't think that this is correctly modeling the problem, because it's only true over long timescales.
Consider this: the average American uses only 7 GB of mobile data per month. Would they be happy with 50 kilobits per second? That's much faster than their average usage rate, so in some sense, the data rate wouldn't be the limiting factor.
It's very much the same with typing speed. Yes, your internal word generation rate might be slower than you type if we're looking at an hour by hour, or even minute by minute scale. But once you have a thought crafted, it's beneficial to get it out as quickly as possible.
