yeah i'm not gonna be an AI company's guinea pig just because the c-suite wants to sign me up. "the results" you mean AI-psychosis and dunning-kruger syndrome?
3-4x from what? There are companies out there that are so dysfunctional and over-managed that they can't code anything to begin with. I wouldn't be surprised if an LLM only solution helped them. I did a contract job that was a week of basic CRUD work for a company, and I was told it took them years to do as much as I did.
I have also seen CEOs do exactly as you're describing, only to find the 3-4x productivity improvement is actually 3-4x more lines of code. And more bugs. Unfortunately there are a lot C-suite people who would rather have captive users locked into a buggy app everyone hates that constantly acts like it's shipping helpful stuff than an app people want to use.
