I remember the magic that was 1GB (and "infinite" because it kept slowly growing) email storage back when Hotmail gave you maybe 5MB. Crazy to think it was over 20 years ago.
i remember using gspace as a firefox plugin to store stuff in my gmail account. it's probably still there in my 20 years old emails.
funnily enough, if it was possible to find the source code of that plugin somewhere, i could probably tell some LLM to cook up some tool to find all such emails and extract the files.
But now E-Mail, like the rest of the internet is so damn heavy, 1GB gets eaten up in no time.
