I'm very envious of your workplace if the stuff before AI was somehow well written. If I had AI 10 years ago I would've been mostly using it to interpret most of the corporate speak e-mails and poorly written technical briefs.
Now I get corporate-speak tech docs in addition to irrelevant internal comms. AI doesn't magically make your coworkers put in more effort. It just puts a veneer of professionalism over the same output.
