The trade off of self hosting your notes is every users phone fills up faster. The trade off of external third party infrastructure/centralized servers is you rely on others to host your notes. The trade off of self hosted infrastructure is that it needs to be maintained. The only solution I see to this is some sort of hashing/compression algorithm distributed via torrents where every note generated has an output that’s shared across users in a WoT which might minimize space but still storage is the primary chokehold overall. The only way we can fix this is we start a Nostr superman 5D crystal hardware server thingy like @Start9 @Umbrel ☂️ where realistically the compressed hashed torrented data generated by a WoT network wouldn’t realistic be filled up unless transhumanism/tree of life/fountain of youth/etc. is accomplished, and we live longer than 120+ years.
