Potentially problematic for those who want to check your findings in 30 years time?
Our use of data has grown so much faster than our network capacity (and indeed, it seems like we're going to hit a series of physical laws and practical engineering constraints here). "Data has gravity" but the only way to "sustainable" hold a non-trivial volume of data for 20 years right now is to run a data center with a big dht that detects faults and replicates data.
There needs to be an immutable, high performance read data store that has a 30+ year plan for survival if we're really going to retool our world around expert systems.
