I agree to an extent that tools are not important.
But, for me, there is a certain threshold that a tool must pass to be useful. A tool that is below this level is only slowing you down or limiting your abilities.
You wouldn't use a knife to tighten screws if you have a perfectly good screwdriver lying around. And there's little to no advantage of buying a new expensive or over-engineered screwdriver.
I believe, plain vi is the lowest I can go for writing code. That doesn't mean that I can't use notepad or nano, but they fall under the level of being useful and only cripple and slow me down.
Ghostty passes this level of usability for me, but personally I'm fine with st - no gpu, no cpu spikes, uses barely any ram and still feels snappier. So, what's the point?
