I already type way faster than I can compose code or prose. 255 WPM would be pure stream-of-consciousness, but I suppose that would be nice to have in some situations.
So do I, in 80% of the cases. However sometimes I think faster than I write, in which case writing kind of gets in my way.
250WPM is at least 2 times faster than I write. That's surreal.
I had the same thought. Maybe for short burst where something is well thought out in your head and all your doing in transcribing. For most coding I find my typing to be more than sufficient. Maybe for something like documentation (but who writes that anyway?).
Even documentation, if you want people to actually read it.
