The transition from assembly to C was to a different layer of abstraction within the same context of deterministic computation. The transition from programming to LLM prompting is to a qualitatively different context, because the process is no longer deterministic, nor debuggable. So your analogy fails to apply in a meaningful way to this situation.
Ultimately itβs about being able to create features within a certain period of time, not just to write code. And in that context the shift from assembly to C and the shift from deterministic programming to LLM prompting seem to have similar magnitudes of impact.
