Except that for railroads I don't need people to convince me about how/when/why it can be useful.
Railroads came out to solve an issue we had (and then it evolved). LLMs are not giving us any new solution, just different speed (better) and quality (worse) to solve things we co&ld already solve.
It's basically the same concept as fast fashion. Worse quality, more speed, possibly more economic. You can change your wardrobe possibly every year, but you will never wear good quality clothes.
Now you can write code at impressive speed, but it is worse in quality, and you need to review it more often than "normal" code.
AI code should always be fully reviewed and put into the correct context to make it useful, otherwise long term problems will void short term benefits
