Tanner, this is a really important discussion. I touched on in a bit in The value of a design education but you’ve done a far better job of saying some of the points I was trying to make, and so much more.
Looking at just UI design tools, we already have an overwhelming number of choices: Sketch, Figma, InVision Studio, Adobe XD, etc. and it feels like new ones are added each day.
I try to ignore them. Maybe in a year or two I’ll think about learning a new tool, but only after one of them has reached some market dominance.
Our profession talks way to much about tools — maybe because it’s an easy thing to write about or because selling them is big business. But in the end, they matter very little.
Your quote “I have never met a designer who got a job because of the tools they use” really resonated with me. It encapsulated the entire point in one sentence. A good designer can easily learn new tools if required. A bad designer isn’t going to get any better by learning or even mastering any tool.
