What Is the Vision for Dank Sharding?

Dank sharding is about introducing data sampling into Ethereum to boost the network scalability. Transactions will still be processed on one main protocol, but it's going to be pursuing a more modular approach to scalability. But I have heard developers saying that maybe folding sharding is not even needed. We've seen that usage of Ether today is quite low and gas fees are very cheap right now.
