They are useful for doing the kind of boilerplate boring stuff that any good dev should have largely optimized and automated already. If it’s 1) dead simple and 2) extremely common, then yeah an LLM can code for you, but ask yourself why you don’t have a time-saving solution for those common tasks already in place? As with anything LLM, it’s decent at replicating how humans in general have responded to a given problem, if the problem is not too complex and not too rare, and not much else.

I sure hope not, the only devices more than a few years old that still function are those with replaceable batteries. Removable batteries make devices simpler, more robust, and longer-lasting. Rechargeable, replaceable, removable, standardized batteries are the sweet spot for sure.
