It seems like the use of ChatGPT is something like "microtasks". Little things a given person could do but would rather not and so is able to delegate to an automatic thing whose output they can verify.
It seems like it's potential as of today is increasing or seeming to increase the productivity of a segment of white collar workers in the fashion that email and the web did (or might not have). A lot of researchers might not have need for this and so not understand this appeal of this.
I, too, have been experimenting a bit to see if/how an LLM might help me. This microtask framing jives with my experience.
One of the best examples so far for me (and it's truly micro) was at grocery store. Friend trying to figure out how big of a rice bag to get and avoid not finishing it before a long trip coming up. She knew she ate a couple of cups dry a week.
"I eat 2 cups dry rice per week. Can I finish a 25lb bag in less than 4 months?" "Yes" (it did show its work).
One shot, perfect response. I know this kind of computational thing is what WolframAlpha was for, but that wasn't nearly as reliable. I know I could figure it out myself, but I'd need to find a reasonable figure for the density of rice and probably do some imperial metric conversions and generally futz around for longer than one would want to stand in front of a pallet of rice bags.
If we're characterizing LLMs as a kind of input interface I'd point out that the first GUI was released in 1973 by Xerox and the first commercially successful GUI was released in 1984 with the Mac 128K. It took 11 years for someone to answer this question. Sure things move faster these days, but we're still only a couple of months in.
With blockchains there was also a fundamental technological breakthrough (I'd argue less revolutionary than LLMs). The problem was that everyone jumped the gun and proclaimed the killer app had been discovered too soon: cryptocurrency's incarnations to date have yet to demonstrate much utility apart from being a vehicle for speculation. Nakomoto invented the first distributed blockchain in 2008...
Anecdotally, I've had more writers (screenwriters and copywriters) tell me they're using ChatGPT than programmers. I think people here might underestimate how big a deal it is in "the real world".
Maybe I should just ask ChatGPT to explain it to me…
