I am always surprised, though at this point I shouldn’t be, that there is always pushback against any attempts at improving the status quo when it comes to typing speeds on HN - as though the creator is attacking all of us with lower typing speeds personally…
From another perspective: sure you might speed up only 0.5% of your workday - but how is that a bad thing?
Repetitive stress injuries aside, even if you only spend an hour a week typing (I suspect it’s honestly more) then if you end up increasing your typing speed by double you’re still saving yourself 25 hours a year. Assuming my a career of 35 years that’s 875 hours and you increase your time fighting imposter syndrome by 0.25%.
Scale up as appropriate for how much time you actually spend typing.
