And also because a good IDE would autocomplete somewhere between 70% to 90% of the result.
At that point one could argue that running your own server to get instant responses from your llm matters, while we are at it, compile times, tests, search queries, could always use be shaved some milliseconds per.
With speed reader tools I can comfortably read and understand 500 wpm, should we now switch to speed readers since we read code more often than we write it ?
No, in reality, you create software faster when the code you write the first time doesn't result in errors, which requires knowledge of your stack.
Even if you are not looking to read your code, LLMs also benefit from good programming practices, some of these programming practices should produce code which is clear, changeable and extendable
I tend to be much more verbose when talking, compared to typing. So, while talking might be technically faster if you measure words/min or symbols/min, I don't think that the speed of actually expressing ideas is higher. Talking just tends to have more repetitions (reiterating the same idea with slightly different wording) and filler words that don't really mean anything.
