I don't think vibe coding replaces website builders. There is value for non-tech-savvy small business owners to be able to update their websites as WYSIWYG drag-and-drop and deploy without ever having to figure out how to deploy their app through v0, Replit, etc.

I run my blog digitalseams.com and personal site bobbiechen.com (as well as my parents' small business site) through Squarespace even though I have the full-stack skills to do it myself. There's just other things I'd rather spend my time on (though to be fair, I'm also fond of Squarespace as I was an intern there).
