That’s how progress works no? Only fix the problems if one sees them. Fast change is driven by negative perception as seeing problems everywhere. Am no coder but I assist dev in terms of workflow and design for 3D geo modelling software. I often have to talk the programmer down when he gets upset, and explain that it’s still great but my job is to find everything that makes me want to throw the mouse at the screen and relay that to him, and that makes me sound negative all the time. Process!
