@Jahrule ChatGPT in it's current version is GPT-3. GPT-2, the predecessor used something like ~15GB to train. GPT-3 uses close to 500GB(495GB or something). More specifically, ChatGPT is GPT version 3.5.
Now, that's all in text, so ENORMOUS amount of data. If it was sounds and videos it wouldn't be considered too much, but words?! That's a ton. If you take the 1 byte equals 1 word, you are potentially talking 500 billion words.
And it isn't just automated. You have people "guiding" it to get right info. Of course you can't go through every step.
Regarding Smartphones, I have one but I rarely if ever use data and it's a Motorola Moto E from 2015. It was $150 CDN back then and I changed the screen and it's functional enough. I have computers for actual compute stuff.
I flat out don't believe in things like Singularity. Ray Kurzweil, the biggest proponent of it I see as a lunatic at worst and delusional at best. It's often said those that don't understand things panic most about it, because likely they don't keep up with it. Also I think it goes against Christian beliefs, because Jehovah won't let it happen.
Things like how it'll cure cancer or disease is Satan's version of paradise conditions promised in Isaiah. If you want to deceive, you need to sprinkle in truth. Then you get confused and don't know what the real thing is, which is called gaslighting. I guess Satan is the ULTIMATE narcissist.
The advancements are impressive but if you look at it every day, it's progression as usual. I think it's good to keep yourself levelheaded.
