I use AI to chew through tedious work all the time. In fact, I let an agent do some work just before I checked HN to read your claim that it can't do that. Everyone at my job does the same, perhaps modulo checking HN. But there's no 'unlimited power' to show you - we're just about 30% faster than we used to be.
In decades of programming I’ve written very little tedious code, but that’s as much about the projects I’ve worked on as approach I use.
