You can patch a bug in code. You cannot patch a model that learned the wrong thing
A software vulnerability lives in a line someone wrote and can be rewritten. An AI vulnerability lives in a learned function nobody wrote, and the most important one — prompt injection — has no accepted fix at all.

Training the model is the one-time cost. Answering your question is the bill that never stops
Everyone quotes the electricity a model burned during training. For anything widely used, that is the smaller number. Here is what a GPU is actually doing, why memory rather than arithmetic is usually the limit, and why published per-query energy figures differ by a factor of a hundred.

Nobody has to break UPI. They only have to get you to press 'Pay'.
Almost no digital payment fraud in India involves cracking encryption. The overwhelming majority are transactions the victim authorised correctly — which is why an OTP protects the bank far better than it protects you.

Your model is 99% accurate. That is usually the first thing to be suspicious about
A model that scores brilliantly on your test set and collapses in deployment is not unlucky. It is the normal outcome of four specific mistakes, and each one has a name, a mechanism and a fix.

An image generator never learned to draw. It learned to remove noise — and that is the whole trick
The machine that turns a sentence into a picture was trained on exactly one task: predicting the static that was added to a photograph. Everything else — the prompt, the style, the strange failures, the copyright fight — follows from that.

Why an AI chatbot invents a fact and says it with total confidence
A language model will give you a citation that does not exist, in the same calm tone it uses for things that are true. That is not a bug someone forgot to fix — it follows from how the machine works. Here is what is actually happening, and what reliably reduces it.

Machine learning, explained without the jargon
Machine learning is behind spam filters, recommendations and modern AI — but the core idea is simpler than the buzzwords suggest. Here is how a machine actually 'learns'.
