For microwaves to produce currents that could plausibly have an effect, there would need to be rectification and resonance, so that current could ratchet up. Unfortunately, both are known to occur in living tissue, as may be observed in people whose dental fillings enable them to pick up AM radio broadcasts.

On top of rectification and resonance, the signal would need to be carried in a place where its current has a persistent effect, and the nature of the signal itself, the modulation, would need to be such as to drive some cellular-scale electrochemical process. It is not possible to predict what that would be for the signal in question, if indeed there are any.

We appear to have got lucky with previous generations, but that tells us nothing about the next.
