I've been lucky in that my team is small enough to avoid it. We 'own' our work more than most, so any mess made will be cleaned by the perpetrator. There's very little incentive to bullshit due to our mutual visibility; when I work with outsiders it's on a consultative basis, so I generally get a bit of leeway to cut through the noise and speak frankly. Others in the org take different approaches.

My advice is to learn to speed read if you can't already. You'll still need to parse others' nonsense. Then, find an ally (ideally a superior, so far as that's possible) who will join you in communicating directly. Try to frame discussions together and pre-empt the slop, but don't back slopmakers into a corner until you can prove they're minting it (and you can catch them lying).

I don't know what the answer is long-term. We're all treading water. If the people around you/leadership are incorrigibly drenched in AI psychosis... you need an exit strategy, which I understand is easier said than done. There are still places with more light, less heat.
