Ruby on Rails generators could build toy projects in like 3 clicks 15 years ago, a Twitter clone being the famous one.
Software engineers still continued to exist somehow.
I'm not saying LLMs will replace software developers, but this is such a ridiculous analogy that it hints to me that you've never seriously tried the latest tools.
There's nothing ridiculous about the analogy. Not only Ruby on rails is better than most vibecoded apps but also "git clone"
It's ridiculous because LLMs are far more capable. There was just a thread on HN the other day where multiple people shared experiences being able to decrypt, reverse engineer, and update the firmware of some long forgotten embedded device with zero background in the field using LLM coding tools. And you're comparing that to a preset generator.
