I have charybdis keyboard with built in trackball, I have hotkey on all my apps, also I don't have to move my hands to use mouse trackball. I mostly use hotkeys in ui apps, I like good ui apps like git fork to view complex repositories, I run circles around cli guys who live in cli (cli is just one off apps for me) when we collaborate or when I drive or teach ppl. Where are some who really good at vim, temux and even tilling vm. I know how they work, I can do things faster in many cases. Eventually it's all about what u like and what works for u, stop comparing workflows, there is always prons and cons to anything, it's not black and white.

GUI requires much more software engineering and development hours than a CLI to create. So yes it makes your a worse engineer; don't wait for someone to expose a feature to you via API and web interface if you can get there via CLI today. Cripes.

It totally does. GUI is for weaklings.
