Why is it so hard to make AI systems reliable and safe in production?

You can build the thing. Getting it to behave in the real world, under real load, with real people, that is a different mountain, and it is beating you right now. That is not a sign you are behind. It is the exact place almost everyone gets humbled. Building is about making something work once. Reliability is about making it fail safely a thousand times. Those are different crafts, and the second is slower, less glamorous, and mostly learned by watching things break. The people who seem to have it just broke more systems than you have yet. Pick one failure mode this week and go deep: how it happens, how to catch it, how to recover. Do that over and over. Reliability is not one leap. It is a hundred small scars, and you are just starting to earn them.
