@simulo In general, my typing speed is rarely the bottleneck of my dev. Perhaps that's because I type at a pretty reasonable pace, and I use languages with very low amounts of boilerplate (and where nearly any boilerpoint can be abstracted away) and in the rare places where there are boilerplate (srfi-9 records come to mind) I have editor support to make typing them in fast through yasnippet.
In general, typing speed tends to correspond to the rate at which I can think, and a lot of the pauses come from needing to get up, pace around, think about the problem, get some tea, sit down again after a revelation. Or playing around with the idea iteratively and discovering the solution.
Lots of people are talking about LLMs as typing assistants and I just generally don't feel like that's a thing I need (excepting the RSI aspects; I do think more voice-driven editor piloting would be a good option to use sometimes)
