End of SF

 
Where is it possibloe to go with SF when things like this are now actualities -- though even David Pogue, tech guru at NY Times, didn't believe it at first:

"WORD LENS When a reader sent me a video of this iPhone app, I wrote back: “Very funny!” I was convinced that the video was fake.

But it wasn’t. You point the iPhone’s camera at anything written in Spanish — say, a sign, headline or restaurant menu — and you see, on the screen, the English translation.

The crazy mind-blower is that you see the original sign — same angle, color, background material, lighting — with new writing on it! Somehow, the app erases the original text and replaces it with new lettering, in the same type size and spacing, but in English. (Spanish-to-English and English-to-Spanish are each $5. The free version demonstrates the fundamental magic by rewriting the sign’s text sdrawkcab.)"

I suppose the only further step would be to miniaturize it so that you could implant it and read not only signs but texts.
