I've had success with Aider from October of 2025 (from my git logs). I have to differ from the general sentiment over here. The tools and models are good enough to make a change in the way work is done. Of course, Big Tech. will move fast and make mistakes but this is qualitatively different from other recent hypes (e.g. crypto/NFT). It has had genuine impact on people and their lives and a lot of simpler jobs with larger teams have been replaced by these models and one operator.
