I think it is not needed to own every line of code anymore , but you should still have control and idea about the architetcure of the system. You should understand what componenets are there and what is the repsonsibility , how are the orchestrated and what are my quality gates where i messure if what i requested match the results. Thats why i build archkeel (https://github.com/rapiddweller/archkeel) and datamimic (https://github.com/rapiddweller/datamimic) ... to increaes the transparency and review surface for human ... to make the results easier to judge ... i think when we stop knowing anything, we can also stop burning token and ressources
