It takes some figuring out but it's been amazing for spreadsheets, I'll explain what I'm trying to do as if I were explaining it to a person and it'll give me a huge script that does exactly what I want, with annotations and everything. It has enabled me to do things that I don't have the knowledge to do and saved me a ton of time. For example, I had a really complicated formula, vlookup, hlookup, arrays, it was a monster of a formula that took me seriously like 12 hours to get working. With GPT, a few years and one pandemic later, I'd forgotten how I did it, so I tested gpt with it. 2 hours. It was frustrating, there were a lot of "nope"s and "got this error"s but it did it so much faster than I could have iterated on it, and that was only 3.5. GPT 4 is way better at that, I can do other stuff just as complex as that with the 25 reply tokens I have.
That's just one thing it's good for, now that plugins are a thing it can use Wolfram Alpha and actually do math (don't even try without that plugin). As a cook I might have a recipe that calls for a liter of soy sauce, but I only have 3/8l, I can just take a picture of the recipe on my phone, pull the text out with ocr, then I have a saved chat where I give it recipes with "adjust this for only 3/8l soy sauce" and it just gives me an updated recipe. I could pull up a note in my phone, multi-window a calculator, and do the math myself, but like why? It's actually a pretty useful tool, at least for what I use it for.
I couldn't give less of a fuck about leaderboards, but I enjoy seasons in D3, but not D4. In D3 you get to max level and get a set of pretty good gear in a few hours. I'm a casual player, I don't play the entirety of the season because I kinda hit my limit and stop getting new shiny things and don't feel like pushing it so I stop playing. Then a new season comes out, I'm like "I haven't played Diablo in a bit, that sounds fun" and I do the same thing, smash monsters and get shiny things.
In D4 the new season landed and I just couldn't be bothered to level again and it really killed the game for me, I'm kinda maxed out on non-seasonal, it gets to the point where you're doing the same thing over and over for hours, or you push harder content where it takes forever to kill something and everything kills you in one hit. I just want to smash shit and get loot, I don't want to level again if it takes more than a couple hours.
Basically seasons can be fun (also they test new content, that keeps things fresh) as long as you can jump right back into the game. Without it you have a ton of legendary items for every class so you just never really need new gear, you just grind for that single piece you need for a 2% upgrade.
Tldr I don't want to grind, I just want to smash baddies, and I'm basically a bird collecting shiny shit. D3 enables that, D4 doesn't. It's all about implementation.
