yeah true - but as with all that data, the proximity of it is in no extent to the same degree as these glasses is going to be.

a 4G chip, literally 1cm from your temple for 8-16 hours a day just cannot be something that is encouraged or that is recommended.

i just can't fathom how that could possibly be safe regardless of your view of electromagnetic radiation - having that against your head for 16 hours a day, 365 days a year. It accounts to 5840 hours of a 1cm differential of electromagnetic radiation to your brain ?

strapping a mobile phone to your head with a 4G chip and letting it sit there isn't something I can see myself doing and the entire utility of the glasses is designed to essentially be "always on" - i can't see you wearing them for 15 minutes and putting them away ? i love that Google are pushing the edge, but maybe they need to invent some sort of electromagnetic radiation wrapper so it doesn't permeate into your brain all day
