> Automation alone did never reduce jobs significantly.

Unless you mean "all jobs across the entire economy", this is pretty obviously false. People used to weave fabrics by hand, make screws and nails by hand, bake bread by hand. These jobs hardly exist anymore.

Of course this did not imply that all jobs disappeared and the economy collapsed. But the sense in which "AI is not replacing workers" is contingent on specific features of software development, not about automation in general.
