At this point, I trust LLMs to come up with something more secure than the cheapest engineering firm for hire.
The cheapest engineering firms you hire are also using LLMs.
The operator is still a factor.
LLMs definitely write more robust code than most. They don't take shortcuts or resort to ugly hacks. They have no problem writing tedious guards against edge cases that humans brush off. They also keep comments up to date and obsess over tests.
And the cheapest engineering firm won't use LLMs as well, wherever possible?
