So never learn anything? Be entirely beholden to other people for everything? People who somehow themselves also have complete knowledge? I've done so many things myself now and that has given me the confidence to do even more.

If I had to have a complete idea of what I was doing to do it, I wouldn't even have a job. Doing stuff and making mistakes is exactly how you learn.

I think you might have reached a nonsensical level of AI contrarianism when it leads you to the statement "doing stuff isn't essential"
