Regardless of whether the project of explainable / understandable succeeds though, everyone should agree it's a worthy goal. Unless you like the idea of stock-markets, resource planning for cities and whole societies under the control of technology that's literally indistinguishable from oracles speaking to a whispering wind. I'd prefer someone else is able to hear/understand/check their math or their arguments. Speaking of 6-8000 years since something happened, oracles and mystical crap like that should be forgotten relics of a bygone era rather than an explicit goal for the future
