Because you can't do this yourself. You don't have the decades of experience to know how to ask the questions and when to steer the tool into a different direction.
Why not? As the AI people say "you can just do things". If there is little consequence to getting it wrong as a parent poster puts it why not? You can learn over time like any other skill.
I want to be wrong (it will affect me and my family personally) - but there is a reason every AI proponent talks about coding and making "coding redundant". For most jobs/industries software is a compliment (e.g. Product Owner, BA, etc) unless that is your main skill in which case it is your main service you are selling. Most roles want to turn software into a commodity or the typical business PM word "resource" that they can acquire as they need - the dream of most business roles (e.g. Project Managers, BA's, etc). It sadly also seems to be low hanging fruit of LLM's; doesn't mean there isn't other aspects to the job of course but coding is becoming "less special" with these technologies especially with common tech and use cases.
