He's doing "engineering" now since he can use LLMs, but he never really spent years doing what we would call software engineering. I.e. building distributed systems, writing terraform/ansible, maintaining old databases or optimizing MySQL indexes, debugging Kafka or AzureMQ, etc.

Don't get me wrong, he's knowledgeable about LLMs specifically, (although his knowledge is rapidly becoming out of date) but he's not a software engineer, which is why his ideas around engineering often seem totally deluded.
