I personally feel that the switch to digital is an attempt to lessen our imprint out in space in an attempt to mask our planet from any other
civilizations who might be using our UHF use to locate us.
after all we assumed we would be able to find other worlds by their radiowave use (even tho we ourselves are now realizing lightwaves rather than
radio waves are a much more effective to carry information ie optical lines).
maybe someone out there cought wind of our seti transmissions or all the other amount of radiowaves we put out into space, and for whatever reason we
decided we dont want whoever heard us to find us anymore, and now were gunna try and reduce the amount of radiowaves we put out there by eventually
changing everything over to digital or optical transmissions.
