I think in terms of moratoria or outright prohibitions, I would distinguish between the use of a technology—the technology of facial recognition—and the uses to which the technology is put. I find it more likely that a ban or a moratorium would make sense for specific uses of a technology than for the technology per se, because for facial recognition there might be useful public purposes including in a law enforcement domain where, despite the privacy restrictions of facial recognition, the overall public good is in favour of using the technology. I would look at it in terms, again, of specific uses for technology. In that regard, yes, it would make sense to prohibit certain uses.
