[Blindmath] Facial recognition -- food for thought

Wed Mar 28 13:04:29 UTC 2012

Apologies to those who haven't seen all of the response postings due to
cross listing of the original post and to whom this post probably won't
make sense.

If I were blind and could purchase all of the necessary hardware, including
gigabytes of USB storage for a few hundred dollars, I wouldn't be sitting
around waiting for Microsoft, Google, Apple, or some other large company to
solve my problems. I would be working to solve those problems myself.

If Bill Gates and Michael Dell had that attitude, there wouldn't be a
Microsoft. IBM would "own" the computer market on a worldwide basis.
