5 years ago we had GPT-3, not even instruction-following GPT yet, a mere completion model. ChatGPT release was late 2022 (3 years ago). True agentic systems with reliable tool calling in a loop, that came maybe a year ago, agentic coding harnesses less than a year ago.

Model improvements may have flattened, the quality improvements due to engineering work around those models certainly have not.

If we always wait for technology to calcify and settle before we interact with it, then that would be rather boring for some of us. Acquiring knowledge is not really that much of a heavy burden that it's an issue if it's outdated a year in . But that's maybe just a mindset thing.
