Reminder: the "blobs get deleted after 18 days" thing is super overrated.

So 4444 means that nothing is permanent on Ethereum? Seems bad to me. I guess permanent content should get sent to Filecoin or something maybe?

We wanted eternal life, instead we got 140 new genders

Filecoin *definitely* does not work by requiring every single node to store all of its content. I think realistically for the Ethereum chain (incl blobs) we want a level of permanence that's somewhere in between "everyone stores everything" and Filecoin.

Requiring literally every node to store the whole content was always an overkill way to achieve permanence. I think each node storing ~1% of the data is probably the right balance. Making each ethereum node also a portal node by default would be cool.
