“Master all prior art before naively trying to do anything on your own” - also, very much does way more harm than good in a learning context. (it narrows the top of the funnel for no good reason)

The gripe seems to be the negative effect on the team, business/project outcome etc, sure work doesn’t pay you to write your own compiler.

But again, its such a disservice to learning to dictate a shape, largely academic, largely top down (vs bottoms up failing & flailing).

No one said anything about learning everything before doing anything, and nobody suggested they were told to do it or how they did it.

And, bad engineers can become good ones. All the good ones were terrible at some point....
