I feel like whoever made that saying never tried to make anything, tools can't replace skill but bad tools can absoloutely make something many times harder than it needs to be which takes energy, time and motivation away from the fine detail that tends to make the biggest difference to quality.
I dunno a jig saw makes cutting interesting curvy bits about a hundred times faster and its really hard to make one. Yeh you can make simpler stuff to do the same job but nowhere near as easily.
