I am not a big AI fan, but you are like the person in the 1970s who said home computers would be a fad because they don't have the power of a mainframe. Just as computing moved from 8 bit processors with a few kilobytes of RAM and no hard drive to pocket "supercomputers" (todays "smartphones" are far, far more powerful than supercomputers of the 1970s), AI is also going to experience an exponential growth in terms of power and capability. LLMs are the current state of the art, perhaps, but that is going to certainly change. The question isn't "is AI ever useful", but rather "is it useful enough today for the specific use case?". That is what this guy is exploring. My gut feeling is that it isn't, but I don't have the experience to know for sure, and neither does anyone else. The very thought of this makes me cringe, but then little boys always cringe when they think of kissing a girl too. Our instincts aren't always "correct." tldr; "only time will tell."
