Perhaps the reason why ChatGPT has become so popular is because it provides entertainment. So it is not a great leap forward in AI or a path to AGI, but instead a incredibly convoluted way of keeping reasonable intelligent people occupied and amused. You enter a prompt, and it returns a result - what a fun game!
Maybe that is it's primary contribution to society.
1. Drafting directional copy I can give to a real copywriter to create something we'd all be happy presenting to users.
2. Act as a sounding board for peer-personnel issues I'm dealing with at work.
3. "Dumb down" concepts in academic journals/articles such that I can make sense of them.
4. Just today it helped me build an app to drill a specific set of chord shapes/inversions on the guitar that I've been struggling with (programming has always been a very casual hobby and, consequently, I'm not very good at it).
Increasingly now I use ChatGPT and sometimes Kagi. And they just work like I expect. I can think of one time that ChatGPT has failed me, which was when I was trying to remember the terms OLTP/OLAP in database architecture. But for a long time now it's been a very effective tool in my toolbox, while Google increasingly wears out.
I use ChatGPT all the time in my software dev job and I find it incredibly helpful. First, it's just much faster than pouring over doc to find the answer you want when you know what you're asking for. Second, when you don't know exactly what you're asking for (i.e. "How would I accomplish X using technology Y"), it's incredibly helpful because it points you to some of the keywords that you should be searching for to find more/corroborate. Third, for some set of tasks (i.e. "write me an example of code that does this") I find it faster to ask ChatGPT to write the code for me first - note this one is the least common of the tasks I use ChatGPT for because I can usually write the code faster.
Yes, I know ChatGPT hallucinates. No, I don't just copy-and-paste the output into my code and press enter. But it saves me a ton of time in some specific areas, and I think that people that don't learn how to use generative AI tools effectively will be at a huge productivity disadvantage.
