So my understanding is each Farcaster hub stores ALL the messages past, present, and future of Farcaster. Will there one day be lighter nodes that only store some? Otherwise, that sounds quite challenging to sustain 🤔. (Also found out Farcaster uses libp2p today, yay!)

Ooh thanks! I didn't know that, I came to my conclusion from this document: https://github.com/farcasterxyz/protocol#12-proposal specifically "each Hub stores all the messages on the network". It's wonderful to hear it's more flexible than that.

no, they only store the last ~1 year of messages, though you can choose to archive older messages in a separate system if youd like to

I think it‘d be possible to shard. The SMT stores all messages in order (based on the time stamp). And you can split that set in all possible ways to decrease node size.
