A non-tech user prompting ChatGPT to write out HTML+CSS+Javascript still doesn't cover the other logistical challenges of hosting it on a server somewhere. E.g. Buy a domain? Then buy web hosting package? Or use Netlify? Amazon S3?

Maybe someday OpenAI will have AI agents with authority to pay with customers' credit-cards and opens Cloudflare or DigitalOcean accounts on the users' behalf. That's a long time into the future where such a workflow would be trusted by non-technical end users. And then you still have the irony of using another proprietary entity of AI to empower users to put up web pages.

Whether the internet was 1990s Geocities or something like Github Pages today, a user sharing content on a personal webpage is not a trivial task. So non-techies compensate with commercial services such as MySpace pages, Twitter tweets, Facebook pages, or examples like this thread's Google Docs spreadsheet. A common theme of all those commercial services is: they took the complexities of web hosting.

Could you not just ask an LLM how one could host this website for free somewhere, and do the same for any logistical challenges that arise beyond that?

I don't think it's a value judgement to say one thing is easier than another and hence people will. Choose the easier thing.

If we want more folks to use and build websites, it needs to be Google-Docs level easy, otherwise people will use Google Docs.
