As above... Especially those which are more geared towards being startups at the present stage.

For context, I am currently overhauling my existing blog (that uses the WordPress framework and plugin ecosystem), and am looking to pivot it into having ecommerce and social network components.

As part of that sunk cost, I'm in no position to change course now.

But despite that... And not taking into account my situation, what can existing websites do (especially those which are startups and which are in the blog, community, ecommerce etc space) to ensure that they don't get overwhelmed by the AI vibe coded onslaught that is going to engulf the market and the internet?

As above... Especially for those who have built their entire businesses around the WordPress framework and ecosystem - either as an end result user, or as a plugin developing producer.

At the same time, what can existing WordPress website users and plugin producers do to ensure that their existing and long-term efforts and plans don't get overshadowed by those who are able to create similar results using "vibe coding" (that requires only a small fraction of the time and effort)?
