Kinda sad that this was done less than 1000 years ago at presumably great human efforts, yet we have forgotten why we even did it.

Lack of record keeping is the key problem.

Will someone 1000 years from now know what you spent your lifetime working on? Will your lifetimes work also be a mystery to future generations and will they shrug and say "all this computer code must be for religious sacrifice, we can see no other purposes for it"?

Is there any way we can make the current era of humanity the 'well documented one', for example by etching all our digital data into diamonds to last millions of years?
