AI isn't at that level. This is by far the most common misconception about AI, and you have fallen for it as well.
AI cannot reliably solve novel problems, nor can it reliably produce high quality work like a design for a bridge. We still need humans to do that. And, the evidence is right before our eyes: bridge architects still have jobs. If AI could do this, all the bridge architects in the world would immediately be fired, since they cost so much more than AI.
I must belabor this point: yes, we have seen AI do really complex things like generate really sophisticated code that was hard and that worked. But that does not mean that these AI can now do all the much simpler things that need doing in a software developer position. It seems like simple reasoning "wow, if AI can do something that hard, then surely it can do something this simple" but that is false. The pattern-matching that AI algorithms use is not the same as thinking a problem through (despite the much publicized efforts at accomplishing precisely this), and AIs still routinely get tripped up over simple things. Everyone who works with AI, including me, knows this, because it happens a lot.
And we have read articles right here on slashdot where harm has come from relying on an AIs work. In particular in legal filings. People keep thinking that AI's work is good enough precisely because it is designed to appear good enough. But it is not good enough once scrutinized.
So, we still need people with the mental skills to do the job. They have to be able to do it without the aid of AI in order to have sufficient competence to, at the very least, review and certify work that comes out of AI.
If we have a generation of students that had AI do their homework for them, and this was acceptable to the teachers who used AI to grade it, then we will have a workforce that is entirely bereft of competence. That will cause serious economic problems with real harmful impact to our lives. And it gets worse. We know that AIs hallucinate. They give false facts when asked direct questions, even if the true facts are available to them. You want those educating our kids?
Well, apparently colleges do, since AI is so much cheaper than teachers.
It appears we are going to have to keep learning this lesson, the hard way, for a while now.
