Could not agree more, it's frustrating that there seems to be such a focus on the 'mechanical' aspect of these keyboards instead of the ergonomic and programmable which are the real stars.
I would love just a low profile programmable keyboard with 5 individual keys instead of the long space bar. That would tick all my boxes.
If I were you, I'd make sure I have a local instance of f.ex Llama 2 and Code lama up and running.
Even though it's not as good as GPT-4, and might even be slower, the value you might get from a local modal in such a case will probably beat most other things. It will allow you to both look stuff up, and even learn new things without needing to copy large parts of potentially irrelevant information beforehand.
