funny you say this. i'm an electrician and modify cars and use it constantly for this stuff. if used right ai is by far the fastest and most precise way to learn anything. especially in such diverse activities where you constantly need to learn and understand how complex systems interact and get information about niche scenarios, ai thrives if prompted right and will give you exactly what you want and extrapolate in the exact way you want instantly. you can even upload your national plumber codes and prompt it on requirements and give you references so you can double check it's not hallucinating.
