I mean, I guess just use chat-gpt instead of Deloitte, seems to be the result of their consultancy. The results will be similarly nonsense, but a lot cheaper.
This. I absolutely cannot understand why a consultancy, who's entire business model is "pay us large sums of money for our expert's advice" would rely on a LLM for even as much as grammar advice.
If your expert is ChatGPT, why do I pay you? I can write prompts myself. This is an incredibly fast way to sink your entire business model- if I were McKinsey or one of the others I'd be out there advertising "We know what we're doing, we don't need AI to do it poorly"
