I don't think this is necessarily true. Software that was mostly tools will be automated because it generally has a "simple" and specific purpose, but consider software that is the final product itself - like a game. LLMs are nowhere even remotely near the level of being able to independently automate the creation of a non-trivial game, though of course they can be a tremendous tool in the creation of such.
And I think that example largely carries over to many other big picture and/or creative tasks. I think it would likely require another revolutionary leap for LLMs to get to that point, and that leap is probably not coming any time soon, if ever, at least not with LLMs.
Another practical issue is that LLMs, as difficult as it can be to imagine at times, are still just glorified autocomplete machines. And so genuinely novel advances will not be coming from LLMs. For instance take LLMs back to the early 20th century and none of them will discover relativity, even with infinite power/time. It's just so unlike their training material, and in direct contradiction to much of it, that it's simply outside their reach, let alone grasp.
