I did overestimate it. :) I actually consider it very likely that good visual prostheses/digital eyes will exist already in 2025, 2040 is more than 2x that (2025-2013=12 12*2=24 2013+24=2037) Very primitive digital eyes already exist: http://www.extremetech.com/extreme/149106-the-first-real-high-resolution-user-configurable-bionic-eye http://www.extremetech.com/extreme/149106-the-first-real-hig...
