Wordpress already killed the low-end of the market a long time ago. 15 years ago, you were setting up wordpress sites and throwing on a simple theme for $500 or so then trying to get them to write up the copy and provide images (or upcharge for those services). Most of this was generally a loss leader with the actual profits coming from charging to manage the hosting for them.
This is the market disrupted by vibe coding and AI-generated copy/images.
These Wordpress or Wix/Squarespace sites account for MOST of the web, but only a minuscule fraction of high-paid devs. For those devs, AI just doesn't change very much because it has no idea what questions need to be asked to actually deliver what management wants let alone the ability to problem solve and deliver novel solutions to issues.
