It depends on where you're using AI. If you're working on a project for yourself or in a tiny company. Then sure, writing the code probably was your bottleneck. But at mid to large companies writing code is maybe 50% of the job, and the other 50% is the process around it. All those processes are the bottle neck, no matter how fast you can write the code. And this was a bottleneck I was hitting well before AI.
I'd put it even lower than that, since there's also the "understand the problem space" portion outside of the external processes and before writing the code.
Yeah, so again the point of text editors is you shouldn't be typing all that much with them. That's why we use them. Macros. Shortcuts. Metaprogramming. Snippets. Identifier completion.
Were people actually typing out the full text of source code before LLMs? Why?
