Has anyone noticed how poorly tools like claude code (the main one I tried) themselves are working? You'd expect software from company with an infinite AI allowance to be unattainably excellent, instead it lags, hangs, flickers, and feels like unpleasant mvp mess. I hear at every corner people telling, how they can 100x now, and if my AI use is not laying prime code it's my skill issue. But where is this excellent AI generated software? Do you maybe have some examples you can share?
