But more generally, the arguments being raised here regarding risk of abuse of the data are predicated on tyrannical or illegal activities occurring. Instead of denying ourselves the benefits of cures derived from data such as this, why can we not build a society where the data is not abused?
Human pro-social activity is a very powerful thing. If there are risks in unifying data, we should work to build a society that stewards those risks responsibly, we shouldn't try to cut ourselves off and hope the life of a data hermit serves us better.
I mean, what other technologies should we deny ourselves? A tyrant can use tanks and troop transports to wage war on their citizens. Should we tear up the roads lest they be abused by tyranny?
