People say it takes at least 6 months to learn how to use LLM's effectively, while at the same time the field is rapidly changing so fast, while at the same time Agents were useless until Opus 4.5.

Which is it lol.

I used it with practically zero preparation. If you've got a clue then it's fairly obvious what you need to do. You could focus on meta stuff like finding out what it is good or bad at, but that can be done along the way.
