Don’t think they are lying about the denial, they said they wanted the upgrade to be big and the z2 is marginally better than what the Steam Deck already has. I would guess a Steam Deck 2 is years away, but we might get a Steam Home Console, or maybe the Deckard VR headset. I kinda doubt any of those would run a z2 though. Why would Valve be using an off the shelf chip when they had a custom chip last time?
I think part of this software at least in the description on the website is easy and reliable detection of LLM bots to block. You can run it and it will generate statistics about bots that get caught in it so you can easily block big lists of them.
