Nowadays, it's the noisy and distracting open office environments where you're scrunched next to people who you probably aren't even working with.
In the future, it's leaning towards remote work. Which sounds great on paper. But there's another whole level of tyranny with that. Only getting 15 minutes per day face to face with coworkers over video chat, the rest done asynchronously over Slack is very impersonal. Though maybe I'd trade that for being able to live in an actual house with a pool instead of squished into a tiny apartment.
