Maybe I’ve been missing some important stuff, but it seems the most relevant and important updates eventually just bubble up to the front page of HN or get mentioned in the comments
Yeah these companies have made unbelievable investments, keeping their products a secret is antithetical to their existence.
Trying to keep up is like jumping on a 90mph treadmill. I have decided to opt out. I think AI (and currently LLMs) is more than a fad and not going away but it's in a huge state of churn right now. I'm not investing a ton of time into anything until I have to. In another few years the landscape will hopefully be more clear. Or not, but at least I won't have spent a lot of time on stuff that has quickly become irrelevant.
I'm currently not using AI or LLMs in any of my day-to-day work.
