A perpetual trust is a legal instrument that is designed to ensure an asset is passed down generations and dispersed in a particular, pre-determined way. Hire a lawyer to help put some non-coastal real estate and some inert metals and some extremely safe index funds and bonds in that and have it rebalance and reinvest every so often and periodically draw off enough from the accumulating interest to pay for whatever a domain and static hosting costs, into the future, plus maybe a little to cover translating a text file into whatever the hell our AI overlords are serving after they’re done with all the genociding.
