It’s hard to know whether complete and utter transparency will realize a techno-utopia of a more honest and innovative future. But, given that privacy has only existed for a sliver of human history, it’s disappearance is unlikely to doom mankind. Indeed, transparency is humanity’s natural state.

Instead of writing code, you feed data to the generic algorithm and it builds its own logic based on the data.
