if you are already competent and you are aware that it doesn’t necessarily give you correct information, the it is really helpful. I know enough to sense when it is making shit up.

Aluminum jeweleries were popular in the 19th century. Light weight and shiny like silver. Then they found a cheaper way to extract aluminum from ore. Then people started using aluminum for industrial applications, made utensils from it etc. and then nobody wanted a piece of jewelry that was made from the same material as a fork. Just wanted to share.
We had air gapped systems (we didn’t have internet) in the 90s and they still got viruses(from floppy disks). I don’t understand what is new?
