This means that the incentive to develop this technology is already there, and so it WILL be developed no matter how much people wish it wouldn't.
The only difference at this point is whether some of the implementations are developed in public view or not. If none are public, then all of them will be done in secret, and our opportunities to develop countermeasures will be severely hampered by having fewer eyes on it, and a smaller entry funnel for potential white hats.
