IMO it is a valid question. Our AI has not yet reached that level, our prompts have not yet reached that level of sophistication. But I do not code in assembly any more, I do not do pointer arithmetic any more, so maybe some day we get to a state where we do not write python also. It is not going to be soon despite the AI bandwagon saying so, there are too many legacy pieces that are not documented well and not easy decipherable due to context window limits. But in 10 years ...maybe prompts is all we need.

PS: Not that we do not have people working at all levels of stack today, just that each level of stack, like a discussion going on today about python's JIT compiler will be a few (dozen or hundred) specialists. Everyone else can work with prompts.
