Hi, author of the blog post here. Happy to address any questions or comments!
tl;dr I believe we are moving to an AI-first world in productivity, but, importantly, not an AI-only world.

For activities like coding where it’s very hard to express your intent exactly to an AI, the hand-editing interfaces, along with collaborative re-use, will remain crucial.
