The criticism quoted wasn't about ethical problems in genetic engineering research. It was about life extension as a goal. I can imagine a debate about that, but I can't see how it is appropriate to create a toxic environment for life extension advocates. Apparently these researchers / advocates found the environment so toxic they were motivated to move. Perhaps they were over-reacting but it seems likely something is wrong. And "move fast / break things" applied to human biology research is entirely an insertion of the commenter, not remotely an implication of Altman's piece.
