Live translation is something I've been dreaming about since Google Glass. I just want translation, subtitles, turn by turn directions, and ad blocking.
I’ll make an exception for ad blocking as long as there’s a visual marker where the ad was.
There's a Black Mirror episode on that (and more), S2E4 White Christmas.
Ad blocking - we'll need a research team and 5 years https://xkcd.com/1425/
The possibility of shooting ads directly into the retina is probably the main driving force behind smart glasses.
