> Was it really that difficult to build a generic website with a template before?

Yes. Code looks intimidating if you aren't used to it (and don't have an IDE). And there are lots of steps between having a file of code and having a hosted website.

I don’t see how a llm solves this. It’s not like a llm hosts the website. Sites like squarespace and Wordpress let you modify your site without ever seeing code. They have graphical editors that you can stay in if you wish. I agree llms help, though if you use a product.
