I'd hazard a guess 90% of WP instances could be replaced by static site generator + some tiny app to handle forms, and the 9/10th of remaining ones with static gen + form + some external commenting system, whether in cloud or something like commento.
Right, but until now, and even today, in most people's early and primitive use of AI, it's been relatively difficult to make that change. To the extent that later this year and next year, people are able to point an agent at a WordPress instance, and iterate with it until it has a parity version of their surface in a custom form, things might start to change.
To be clear, I'm not one of the people who believes that software is going away or that UX is going away. I think those are both still very important. But I do think that a lot of legacy software can be replaced, and then we'll end up with a new level of software in the longer term.
Or maybe the majority of those people have crappy WordPress websites because they got some social proof that having a website equals making more money, so they scammed some freelancer out of some hours and hey presto.
Then the social proof moved to proprietary darknets, e.g. Facebook pages, which is easier - you don't have to learn anything.
I've seen no local small business care about its webpage, but I've seen a lot of them painfully struggle with crappy LOB smartphone apps.
I expect software and UX to only decline in quality.
