An excavator can also lift rocks that I can't. But that's really beside the point.
It doesn't really matter which analogy you use, the fact is that I can do what an LLM can do, in my field. I can probably do a better job, because I know more current web APIs than an LLM has had time to train on because of limited human output.
You don't get faster results with more developers though. You don't make a baby in one month with 9 mothers either. You might have seen a small increase in development time with more than one dev on a single project but that doesn't scale past more than a handful of devs, usually. At least not per feature.
