What benefits do zk rollups have over their optimistic counterparts?

With an abundance of projects launching and giving away airdrops. My question is what killer app or innovation did blockchain bring? Please don't tell me it's eigen layer or some fast blockchain with 'x' tps. Why would a normal person want to use it? Why should they care?

I wonder if there's any discussion about zero knowledge on lens at all.

Lens on orb feels pretty good. But mass adoption? Will be reposting a post I made on Nostr (another decentralised social media protocol).
