Because whatever you use a LLM to build will inevitably need more features added or some kind of maintenance performed. And now you're spending $200+/mo on LLM subscriptions that give you a half-assed implementation that will eventually collapse under its own weight, vs just buying a solution that actually works and you don't have to worry about it.

Not to be argumentative, but I have a concern that whomever I buy my solution from will have vibe coded it instead. I guess that means my support contract entitles me to hassling them about it, but I'm starting to worry it's just LLMs and vibe coded apps all the way down.
