Agreed. Been experiencing this firsthand with an app I've been building myself. Vibecoded a working prototype ridiculously fast but then came the optimization issues. Since mine is very hardware dependent every different brand, oem stack, processor, video card, and every little thing changes how my app functions and a lot of it isnt even documented properly. Now AI is still very useful here, but you actually need to know what even to ask and fix in the first place
