Dappnode aims to make it accessible for everyone to run infrastructure. By running your own infrastructure you get privacy by default (no RPC provider can read your txs and queries and link your wallets). 
In the case of interoperability, you can run L2s (Optimism, zkEVM) and sidechains (Gnosis, Matic) and L1s (LUKSO) and hopefully new bridges will emerge that have decentralized keepers that users can bring.

The biggest elevation here happens with UX, where Dappnode is de facto the best way of running nodes in a self-sovereign way, and for most non-technical users, also the only way. We believe this UX piece is KEY to expand beyond people that are technically gifted and bring self-sovereignty and decentralization to everyone and to the networks that users want to support.
