You can't completely make the comparison with farmer. There is limit of land that can be farm and there is a certain amount of food need to feed humans and animals.

Software dont have such limitation, anybody could be making software as long as there are users for it. I thing Ai will help developer to be more efficient in the short term, middle term Ai will help regular fox to make software with no code solution, long term if we get AGI then it is game over for SWE but every other job we know too
