> Even if there is a "fully vibe-coded" product that has real customers, the fact that it's vibe-coded means that others can do the same.

I think you are strawmanning what "vibe coders" do when they build stuff. It's not simple one-shot generation of eg twitter clones, it's really just iterative product development through an inconsistently capable/spotty LLM developer. It's not really that different from a product manager hiring some cheap developer and feeding them tasks/feature requests. By the way, competitors can hire those and chip away at your moat too!

> Unless you have a secret LLM or some magical prompts that make the code better/more efficient than your competitions, your vibe coded product has no advantage over competition and no moat

This is just not true, and you kind of make my point in the next sentence: many companies competitive advantages come from distribution, trust, integration, regulatory, marketing/sales, network effects. But also, vibe coding is not really about prompts so much as it is product iteration. Anybody product can be copied already, yet people still make way more new products than direct product clones anyway, because it's usually more valuable to go to market with stronger, more focused, or more specialized/differentiated software than a copy.

Friendly reminder: the comment is under a post that is hyping the capability of LLMs.
