Technology (or cover-up of technology) lessening the harvest?

[Patrick]

I am Ra. Your peoples have, at this time/space present, the technological achievement of being able to create and fly the shape and type of craft known to you as unidentified flying objects. Unfortunately for the social memory complex vibratory rate of your peoples, these devices are not intended for the service of mankind, but for potential destructive use.

Here they are saying that because these 'UFOs' are not intended for the benefit of mankind, but for 'potential destruction', that it is lowering the overall vibration of our entire Social Memory Complex.

I don't know, it seems to me that Ra is saying that unfortunately it is not used to help us increase our vibratory rate.  Not that it is lowering it per se.
