Chat puts conversations on conveyor belts that are perpetually moving away from you. If you’re not at your station when the conversation rolls by, you’ll never get a chance to put in your two cents. This means that if you want to have your say, you need be paying attention all day (and often to multiple rooms/channels). You can decide not to follow along, but then you’re battling the fear of missing out. It’s a bad bargain either way.
