There have been constant questions about what would happen to Rollups once ETH2.0 is fully complete including sharding.

"It will not become useless for a long time. The current proposed implementation of sharding is just data sharding, meaning that you would not be able to have txs “directly” on the shards; rather, the shards would just be data space so that rollups could have much higher scalability."

Rollups are here to stay even with ETH2.0 sharding folks.

Super bullish for Optimistic Rollups like Arbitrum, Optimism, and Boba Network. Unfortunate that Boba Network is only one that is tokenized (fees still paid in ETH), which will help decentralize the rollup.
