I'm all in favor of talking about drawbacks of AI coding and potential future problems. No problem. But at this point just the blanket statement that you'll never use it is not reasonable. It's the equivalent of a master car mechanic seeing a robot that can pretty reliably rebuild a transmission in a few minutes saying "I'll never use that; I'll always do it myself." Okay, sure buddy. You keep taking 8 hours to do what now takes everyone else 5 minutes. Knock yourself out.

LLMs are fundamentally chaotic and unpredictable. They cannot do anything reliably.

almost everything he says is reasonable and correct though. using AI does undermine understanding, and companies hiring less juniors will be the death of them. Also juniors using AI will be the death of deep understanding if they continue. Robots fixing cars is not an apt analogy because it's a rote task. LLMs are being used for far beyond rote tasks and that's where the danger lies. People forget that most frustration and struggle are crucial, not something to remove. And people especially beginners do not have the judgement to know when struggling is appropriate.

By analogy, you can imagine a mid-century human computer shouting "I will never use computing machines to perform numerical calculations! I must perform every addition by hand!" You can even imagine a commune forming around "hand-made calculation" and trying to sell services that are certified "automation-free".
