It does need to be reliable, though. LLMs have proven very bad at that
That was the way I saw it for a while. In recent months I've begun to wonder if I need to reevaluate that, because it's become clear to me that scaling doesn't actually start from zero. By zero I mean that I was naive enough to think that all programs, even the most googled programmed one by a completely new junior would at least have, some, efficiency... but some of these LLM services I get to work on today are so bad they didn't start at zero but at some negative number. It would have been less of an issue if our non-developer-developers didn't use Python (or at least used Python with ruff/pyrefly/whateveryoulike, but some of the things they write can't even scale to do minimal BI reporting.
I actually imagine it's the opposite of what you say here. I think technically inclined "IT business partners" will be able of creating applications entirely without software engineers... Because I see that happen every day in the world of green energy. The issues come later, when things have to be maintained, scale or become efficient. This is where the software engineering comes in, because it actually matters if you used a list or a generator in your Python app when it iterates over millions of items and not just a few hundreds.
