Deployment is only an issue because it's assumed to be unnecessary in a current environment. As that assumption changes, so will the default setups. Of course that introduces new vulnerabilities, but as LLMs also make a mess of everything security related (and future LLMs will likely make a mess current era 'LLM hardened' setups, onward) our approach towards security and the internet will change in ways that are difficult to predict today.

I agree that plenty of people are currently hesitant to use LLMs for technical purposes, but I don't think it's because they literally could not do it. LLMs will now code up entire workable apps from minimal/vague/contradictory descriptions. If somebody only got to a landing page it's because they only prompted for a landing page, possibly trying to mimic how a human developer might have previously built a site - and quickly getting lost. But if you just say 'make a website where people can order widgets, manage their orders, and do all related tasks' it'll get done, no technical knowledge needed.

So I think we're mostly in a transitory phase. As people realize how powerful these tools have become, adoption is simply unavoidable.
