No amount of LLM usage is going to change them into full stack vibe coders who moonlight as sysadmins. I just don't see it happening.
Not until, that is, a new generation, that has grown accustomed to the tech, takes over.
Until then the current SMBs will for the most part fulfill their IT needs from SaaS businesses (of which I think there will be more due to LLMs lowering the barrier for those of us who feel confident in our coding and sysadmin skills already).
