Yes and no.

Let's first settle on the definition of vibecoding so that we're not miscommunicating over definitions. I'm using the one that seems the median definition nowadays: >95% of the code written by LLMs, <60% of the output code human-reviewed, meaning there's a large part of the codebase that no human ever reviews.

As you said it's about time invested in thinking about it, yes. But remember that even pre-AI >90% of software got never used, it was dead on arrival. Look up "success rate of software projects in business".

You can put lots of time into thinking and vibecode everything. You can put very little time into thinking and write by hand. Of course, vibecoding makes the former much more likely. But nothing about it is inherent to it.
