What's cool (and tough to keep up with) with this wave of tech is just how quickly it moves.
On the plus side there's a lot of interesting things and it is generally easy to follow/figure out what they did.
On the minus side it's a little exhausting, and there's so much money in it feels like the vast majority of it is grifting. To add to that, the people who are trying to catalog it (the AI guy on LI) are the griftiest of them all.
I've found the best way to keep up is find one topic you want to learn about, deep-dive, and read all the related papers, then explore breadth-first from there until you find another topic...
