They also have another problem I haven't seen addressed.  People are 
talking about Turing-test type challenges to prove you are human.  So 
far all the ones I've seen proposed require that you can see.  They 
will not pass federal requirements in the U.S. as they currently 
stand.  And if they get widely deployed outside of the federal arena 
you are certain to see accessibility lawsuits.  Solveable perhaps by 
including both visual and audio prompts, but someone should start 
thinking about it now.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
