Yeah, I remember speech recognition taking decades to improve, and being more of a novelty - not useful at all - even when it was at 95% accuracy (1 word in 20 wrong). It really had to get almost perfect until it was a time saver.
As far as coding goes, it'd be faster to write it yourself and get it right first time rather than have an LLM write it where you can't trust it and still have to check it yourself.
