All gene related technologies do. But as is the case for all of them, extensive testing and quality controls need to be in place, given how their flip side can be devastating.
Well... I think current testing on these technologies is more than sufficient for keeping human lives safe. That said we can't protect against unknown unkowns. Aka you can't test for a problem you don't know.
As always I think concerns over this technology is overblown. With regards to the basis of the technology of course. Concerns over multinational business practices are reasonable.
Anyway, keep up the content.
