I meant that every time our programming has taken place further away from the raw hardware, we've created abstractions that allow us to think at a higher level, allowing us to build larger and more complex systems. That also let more people write code.
I believe that programming with AI means no longer thinking in terms of strings, lists, and dicts, even though they're clearly being used by a lower level (assuming that AI is writing Python). This is similar to how we don't think in terms of bits and registers, even though those are still being used at the even-lower level.
I'm starting to think about what abstractions we'll want to create and use at this higher level.
