I think a whole lot of people who are worried about environmental damage from this robot are not realising that even though it's advertised as autonomous it only operates for a few hours before needing a recharge and as such it can be turned off very easily if things aren't going right. The ocean is massive. Even coral reefs are massive. A fleet of these robots (which they don't have yet) would take years to affect significant areas. This is a totally different ballgame to humans previous experiments involving introducing an organism to do pest control in a new environment.
