Use of AI seems to be a regression in this regard, at least as currently used - "look ma, no hands! I've just vibe coded an autopiliot". The current focus seems to be on productivity - how many more lines of code or vibe-coded projects can you churn out - maybe because AI is still basically a novelty that people are still learning how to use.
If AI is to be used productively towards achieving business goals then the focus is going to need to mature and change to things like quality, safety, etc.
With humans and code reviews now two humans looked at it. With LLM and code review of the LLM output now one human looked at it, so its not the same. LLM are still far from as reliable as humans or you could just tell the LLM to do code reviews and then it builds the entire complex product itself.
