> Practically speaking, is there really a difference between prompting an LLM to create a CMS for a website and installing something like WordPress or Ghost?

There is some difference; when you install WordPress or Ghost, your problems are shared. There's a community that goes along with the software and a "shared understanding in the world" of how it works and where the rough edges and limitations are. A lot of the time, LLMs will actually be better at modifying WordPress or Ghost to do what you want than they will be at fixing the CMS you built last Tuesday.

When you custom build, you can get an exact fit for your needs but your misery is yours alone.
