I’m so glad this post is still around. I cite it a lot when discussing creative tools with people who think that visual is the only way to go.
Obviously the best computer tools offer both visual and textual ways of working. But if you have to pick one, bet on text.
I was about to add a caveat about pure visual tasks, like image composition, but advances like DALL-E are starting to put those tasks into question as well. If I were making a photo editor today, I would bet on text.
