from my pov, tech people are still primarily on X. like 90-95%.

Meta's gemma team was on X recently looking for advice on MOE and reasoning for gemma.

Qwen announces on X: @Alibaba_Qwen or @JustinLin610

Basically all of linux and programming happens on X.

discord for sure has discussions. LM studio pretty much only exists there. Reddit is most just dead internet at this point.

Freenode's hostile takeover during covid pretty much ended irc. An official end to the IRC era.

>Where did they go? I have found a few, but not many, on Mastodon and Bluesky.

The USA dominates tech to be sure, so the USA political polarization would disproportionately impact this sure. But it was temporary as mastodon and bluesky declined and everyone seems to be back to X.
