I'm a backend dev and I've been wondering if structured AI productivity training is worth it for people who already work in tech. Like, I already use Copilot, I can write decent prompts, I know what an LLM is. Does something like this actually add anything I couldn't figure out in 30 mins of Googling? Asking because a non-technical friend of mine (marketing) swears it transformed her workflow and she now does things in her job that her whole team can't. But I feel like I'd just be bored in a session aimed at beginners. Do any devs here have opinions on structured AI upskilling vs just experimenting yourself?
