@eurogee, this discovery is so mindblowing. Knowing that blind people can actually see with this sensor on their tongue is so revolutionary.

However, my question is how long will it take for this technology to reach every common blind man out there in order for them to improve the quality of their lives?

Anyway, I really look forward to the accessibility of this technology to people who really need it.

Thank you so much for taking the time to share this us.
