I can't think of anything off the top of my head that isn't just doing the things that make it a generative AI. (It's better at generating an image that I describe to it, etc, but that's not something that another technology does.)
I, a below average programmer, can write code myself but it takes time and effort that is generally incompatible with my actual job. With an LLM I am able to write code with a level of time and effort that fits very nicely inside my job.
It can figure things out in a fraction of the time that it would take me. The limiting factor is no longer the depth of my technical knowledge but rather the knowledge of my business.
Sure, I could hire someone to do the coding for me but with an LLM available, why would I? And in that situation I would have to teach that person about the business because that would become their limiting factor if they could code as fast as the LLM.
I'm doing mostly scripts (some Python but mostly Google Apps Scripts) to automate processes at a digital marketing agency. As long as I can clearly explain how our business works and what I'm trying to accomplish I'm getting working first drafts of things that would take me hours to write (a way worse version of) in 30-40 minutes – and 25-35 minutes of that is writing the prompt/documenting the automation I want made.
It's really been amazing for me.
Is it better than google search 20 year ago, when "google-fu" was a thing (look it up, google-fu refers to the ability to "ask a far more nuanced question about the kind of information you are looking for").
