This obviously isn't a binary question. Sure we cars have benefits but we don't let anyone ducktape a V8 to a lawnmower, paint flames over it and sell it to kids promising godlike capabilities without annoying "safety features".
Economic benefits can not justify the deaths of people, especially as this technology so far only benefits a handful of people economically. I would like to see the evidence (of benefits to the greater society that I see being harmed now) before we unleash this thing freely and not the other way around.
