In my case, if you are talking about startups specifically, its true. I've been an engineer now for 15 years. About 5 years ago, long before LLMs became a thing, I got to the point where I stopped using stack overflow and google for most things, only using them for the hardest, most complex questions. Thats how I use LLMs nowdays for technical things, which is not often. Business however is new to me.

As a solo founder, i've got to be the ceo, marketer, product manager, customer service rep, tech support person and a bunch of other things i've not previously done. GPT-4 is great at guiding me on these things. In a typical 2 person CEO/CTO founded early stage startup, the CEO might be doing these non technical things until the business gets enough funding to hire their first employees.
