As far as ecosystem impact goes, it seems Verily's approach can be easily controlled as they releasing roughly the same number of mosquitoes as they are eliminating from the fertile population. This contrasts with the gene drive approach, which has recently been shown to be successful at eliminating populations albeit in an experimental setting [1]. Given their theoretical ability to spread throughout an entire ecosystem within only a few generations, it seems like that is a potential panacea though with a much higher risk of unintended consequences.
