If you're not being sarcastic, you answered your own question. LLMs can absolutely do whatever you tell them to, which rapidly leads to the creation of a dependency if you begin building upon that as an assumption.

I've, for better or for worse, jumped full-on in with LLMs, and I can already feel my abilities radically declining over time. That's fine by me, but if you're a company looking to protect your institutional advantage - just handing over everything to an LLM suddenly means anybody can do exactly what you're doing, literally. At best and this is an absolute best case scenario, you're transferring your advantage to the stewardship of another company.
