Twitch has offered VODs ("videos on demand") for streams for a number of years now, and people who can't see all the streams generally have at least a week to catch up on any content they particularly wanted to see. Skimming works particularly well if you just want the high points. Where Twitch's live model works really well is in having a community of people all watching together. Streamers often engage with their audiences in some way, and Twitch's recent move to offer lower-latency streams is a reflection of that. There's a recent craze for a marble racing game called "Marbles on Stream", which a streamer integrates with their Twitch chat so that viewers can type `!play` to enter a marble into the race. (It's a Skinner box if I've ever seen one, but I like Jelle's MarbleLympics on YouTube, so I'm not one to talk.) You couldn't do that with recorded content.
