It's all well and good to be worried about the privacy implications. The real question is, what can we do about it? Are we going to enact a ban on Google Glasses - along with any portable image and audio capturing device - and hope that people willingly play along? How will we enforce something like that? At some point, we're going to have to accept that for better or worse, any notion of 'privacy' in public spaces is dead. The only thing we can do is adapt.
