[Blindmath] Facial recognition -- food for thought

Wed Mar 28 21:54:44 UTC 2012

Steve,

You wrote "My point here is not to scold as we have been sort of scolded,"

My earlier post was not intended to scold you or anyone else in the blind
community.

I pointed out when I made the (apparently offending) statement that it
might not make sense to some readers due to those readers not having seen
all of the previous posts due to distribution issues with earlier posts.

My post was in response to a post made earlier by a SIGHTED individual, I
repeat a SIGHTED individual, who in effect said that we shouldn't expend
efforts doing things that the big companies might do better if we are
patient and willing to wait long enough.

My point is that if I had the need, (and perhaps there is no need), I
wouldn't be patient and wait for something that the big companies might do
for me at some time in the future. Instead, if possible, I would do it for
myself.
